thats the max speed you can get on Arduino uno as the max clock we can generate on gpios is 8Mhz as arduino runs at 16Mhz and fps is calculated as (pclk*5)/4000000 substituting pclk as 8Mhz we get 10fps
Hey! I was able to get the Arduino to be in perfect sync with the camera. This means that I don't have to check pixel clock while reading a line from the camera. It just blindly reads next pixel and sends it out from the SPI.

Hey, man! This video was amazing! I reaaly apreciate your job. But I need some help, i am trying to use this camera to identify colors and to get how much bytes per seconds i can get. Can you help me?
Thanks Indrek! This was my first ever Arduino (Uno) project and your video provided EXCELLENT instructions! Before I set it up on a nano and built it into an automotive rearview parking camera, I'd like to try and improve the screen brightness. I see that the screen can be powerred by 3V or by 5V. Would converting to 5V on the screen power increase its brighness? Could one keep the signals running at 3V? Thanks again for the fantastic video!
I am pretty sure that it won't get brighter like that. If you leave J1 connection on the screen board open for 5V then the AMS1117 voltage regulator (just above the J1) will step the power down to 3.3V. You probably could try to scratch the tracks for LED power on the board and add your own wires with higher voltage and a current limit resistor. Note that PIN "7-BL" on the screen board is not power to the LEDs. It is just a signal that turns the back light on. LEDs are powered by the VCC PIN. (I thought at first that this PIN provides power to the LEDs)
Thanks @@IndrekLndrek. I have now bought the components for making my application version using a Nano, voltage regulator for the automotive 12VDC incoming power, carefully designed strip-board layout for the resisters, fuse, power switch, shielded multicore cables etc. I'll 3D print the enclosures and I think the project will be a nice success, again thanks to you for working it all out!
The longest cable I have tried between Arduino and the camera is about 20cm (a ribbon cable). It would be interesting to know how long distance you can make it.
Hi @@IndrekL. I finally got around to building my application version with the Nano. The cable to the camera is 1.5m and the cable to the screen is 0.5m long. I set the adjustable DC-DC regulator to 9V to supply the Nano. During the wiring up, I conducted your red screen test and your green screen test and both worked correctly. However, when the wiring is complete and I turn on, only 2/3rds of the screen comes on with a fuzzy snowy image. Nothing close to how well it worked before with the Uno and the breadboard setup. Do you think the cable lengths are too long and attenuate the signals too much? Or do you think I made a mistake on something? How would one troubleshoot? connect up to oscillioscope and check out the signal voltages and digital signal crispness? Or should I take the whole thing apart and go back to the breadboard version, but using the nano and then build progressively toward my application version?
@@garethfloweday8030 I think that most likely the cable to the camera is too long. Could you try with a shorter cable to the camera to make sure? I think it would be better to put Arduino near the camera instead of near the screen. There is only one way SPI communication to the screen but to the camera Arduino has to generate system clock and then read back all the pixel data.

Hello Indrek, I am stuck with a project could you please help me out somehow? The main idea is based on your project though ours is intended to save the captured images to an SD card. Unfortunately we could not figure out the correct method for this procedure yet. We would appreciate your help in any form. Thanks
I plan to learn Arduino and was thinking of doing a project using a live cast on an LCD screen. Instructions very clear and simple, will definetly try it out. Do you think it would be possible to connect 2 screens simultaneously to the camera?
Maybe you can wire the same connections to two screens. In theory it might be possible since data only flows from Arduino to the screen. I haven't tried it myself though.
@@QqsMinutesaPerdre i imagine if you wire all the pin connections to the arduino into a breadboard and connect the two screens like that it should work. Did a similar thing with two different modules using the same arduino connections and it worked fine👍
How can I get the image displayed on the display to move to the right or to the left (according to the amount of rotation) by turning a potentiometer left and right?
You probably could use the same connections and the same code. It would be better to use WAVGAT nano instead of Atmel based Arduino since then you get 20 frames per second which is much smoother. The hardest part is to make a 3D printed body for the device and custom PCB to fit into the body.
@@IndrekL Brilliant idea to use the WAVGAT , as i have LGT8F328P sitting doing nothing, and can double the Mhz from the UNO to 32Mhz and cheaper than Nano too!. Thank you!

@IndrekL Hey ! How to put the code on the Arduino IDE and then upload it to the map? I downloaded the code but I can’t put it on the app! I thank you in advance for your answer.
Ok. I have 1.8" display as yours, but it isn't same. alexnld.com/product/1-8-inch-128x160-spi-serial-tft-lcd-display-module/ - This is mine. Can i use it with yours code?
You should use FIFO version of the camera if you want to store the image onto an SD card. The problem is that writing to SD is too slow and Arduino doesn't have enough memory to buffer the image inside its RAM.
Hey I m following your project, i m using 1.3 inch TFT display with ST7789 driver any suggestion like what should i change in your project to make it work ?
Hey! The main problem with the Adafruit's screen library was that drawPixel and even pushColor are too slow. So I added startAddrWindow and endAddrWindow so I can just write pixel data directly to SPI without having to toggle the chip select pin between every pixel. So you probably need to make the same modifications to the screen's library you are using.
Yes, you can also connect servo motors to the Arduino in addition to the camera. For example here I am using the OV7670 camera to track the black line: ruclips.net/video/HW2iLS1DyNA/видео.html Although Arduino is very weak. You can't do very complex tracking with it.
How to send this live image from one arduino to other arduino and display the image on screen of other arduino? for wirless transmission , we using XBee module
Thanks a lot sir... For sharing this project... Just one thing... Can you make the video from the camera save to a SD card...I won't mind if you use any other board(esp..stm) for this purpose... As the Arduino might not have enough juice to control...
The main problem is that saving to SD card is slow process and Arduino doesn't have enough memory to hold the whole image before saving it. In this case it is probably best to use OV7670 with FIFO. Then it could even be done with Arduino since FIFO saves the image quickly and then there is enough time to read it out and store on the SD card. I will think about it. Maybe I will try it some time in the future.
@@IndrekL but can any other board be used for this purpose as stm32 or esp ...? Coz OV7670 with FIFO memory is quite costly... Anyway thanks for replying so fast...😣
The cheap STM32 "blue pill" board (stm32f103) has much more RAM than Arduino Uno/Nano (20KBytes instead of only 2KBytes) but it isn't enough to hold even one frame of 160x120x2 (2 bytes per pixel). Although maybe it is enough to buffer image while writing it to the SD card at the same time. ESP8266 maybe if there is a model with enough IO Pins (The camera needs at least twelve - 8 for pixel data + 2 for i2c communication + vsync + pixel clock. Optionally additional 1 to generate xclck). Mabye pixel data could be written into a shift register and then read out over SPI. If you could find a cheap SRAM chip that is big enough then even Arduino could first store it into this external SRAM chip and then later copy it over to SD card. I am sure that there are microcontrollers that have enough internal memory but I doubt that those are cheaper than the OV7670 with FIFO camera.
Hey! Getting a new display to work with it is a process. I can't just tell you how to do it since I don't know. You have to expermint with it. I had to modify the screen library to get it working since the original libary code was too slow.
theoretically, at the transmitter, you could use an nRF24L01+ RF transceiver module in place of the screen since it uses the same SPI bus and, at the receiver you could connect another nRF24L01+ module to an arduino which is connected to your PC via USART to display the image data
@@SopanKotbagi Hey! I checked, the nRF24L01 seems to support up to 2Mb/sec data transfer. It should be doable with minimal code modification on the Arduino side, but with a lower frame rate.
Hello, Indrek! Your building is cool! I want to build it own, and I have some results. My actually problem is with fps of the OV7670. I search that the fps of it, I can control with the certain types of registers inside the camera, but I do not understand how exactly do it. Can you recommend how to increase the fps of it? P.S. I tried to decrease the resolution, but it was not enough.
@@IndrekL Now I use the UNO to testing the camera, then I will move the stuff to the Mega to get inputs from other sensors. So, to change the fps of the camera I should change the clock pre-scaler parameter of the Arduino? If it is, then what is the range that Arduino UNO has handle the camera byte sending, because in some article I read that UNO can not handle the data with speed of 8 Mhz?
Indrek here I have another issue, if I will decrease the pre-scaler value to 3, then I haven't get the image. I work with resolution of 160x120, and if fps is 5 that is enough for me. But I can not get it. My purpose is to send the image to my computer through the serial port. Maybe for that I get the low fps? My PCLK 8MHz, my setting pre-scaler value is 13.
nice idea. I'm looking into doing this with esb32cam. Cheaper cam and uc in one unit. My son wants night vision, so basically this with a hefty ir flash light that is shoulder mounted or something
I compressed the sending of bytes over SPI as close together as possible. If you use Arduino library's "spi.write(data);" then it leaves huge caps between two byte. I write directly to the SPI register; SPDR = byte; And then just wait until a byte is sent with asm volatile("nop"); And then send the next byte.
Hello sir I have an doubt that is it possible to operate 3 or 4 lens output capture only photo and send that to our gmail Is it possible sir by using one arduino or raspberry board.
Hello Mr.Indrek Luuk, Can the SPI data to TFT be sent by LRF24L01 type data link to make wireless capture at PC? If so, will it need 2-way communication or just one way? I need to remote capture low resolution image and send by RF data link.
I Googled the LRF24L01 and it seems to support data transfer speed up to 2Mb/sec. This is almost good enough. It could work if it is OK for you to sacrifice some resolution or frame rate. The SPI to the screen is 8Mb/sec. For the images you only need one way communication.
Thank you I just need one image grab in lowest resolution. QCIF or QQVGA (160x120) monochrome is fine, I just need to monitor a device state that has no output.I do not mind slow transfer of 2-3 seconds per frame as I believe the 2Mb/sec is a little optimistic. I would prefer image size
This sounds reasonable. A QQVGA frame (with colors) from the camera is 160x120x2 = 38400 bytes. Getting it to work around 1fps shouldn't be too hard. Probably 2fps is not impossible (there is always overhead and timing has to be perfect) People ask a lot about wireless transfer of the image. I just ordered a couple of LRF24L01 modules myself. When I have time I will try to do it myself also.
Hey! You need to get: 1. Arduino NANO (a clone is fine) 2. This screen: www.ebay.com/itm/1-8-Inch-Mini-Serial-SPI-TFT-LCD-Module-Display-with-PCB-Adapter-ST7735B-IC/401010353521?epid=1748378921&hash=item5d5e146571:g:48EAAOSwA3dYgbyi 3.

But if you do it on a bread board you will be better off using resistors as simple voltage dividers. I tried to use those level shifters on bread board first but the image wasn't clear. Something produced too much noise.
Ah, ok. I designed it myself and you can't order it anywhere in assembled form. If you download the LiveOV7670 project files from github then you can see that there is this folder: LiveOV7670/pcb/kaamera_ja_ekraan/gerber/ If you zip the "gerber" folder then you can upload it to oshpark.com and get it manufactured. I ordered this project from OSHPark. Or you could use a Chinese manufacturer like PCBWay. Chinese manufacturers are cheaper if you want bigger or more boards. When you receive the board you have to solder two 10k resistors and a bunch female pin headers onto it.
@@IndrekL ah okay thanks! Is there anything else beside an arduino that can take the camera input and output it to a 2.8 inch lcd? Trying to get as high of an fps as possible
Hey! Try checking the XCLK and Pixel clock wires. If those give bad signal then the image quality will get bad. Make sure that the connections are good and that the wires aren't too long
I bought OV7670 camera, but still didn't try it. Can i use Arduino mini? Powered with 3.3V and skip all that level-shifting? Will code work if i use arduino micro on 8MHz?
How exactly are you trying to do the library install? If you just copy the two library folders (Adafruit_GFX_Library and LiveOV7670Library) into Arduino/libraries folder then it doesn't give any errors.
hi again, I'm trying to mirror the screen about the y axis. From the internet I've got that I should change MY in the MADCTL register. In your code the MY bit is set: "#define MADCTL_MY 0x80". Looking at the ST7735 datasheet there is a table (page 55) which I think explains what I should change '0x80' to. However the table doesn't make sense to me - could you take a look?
Hey! I tried it. In Adafruit_ST7735_mod.cpp "void Adafruit_ST7735_mod::initR(uint8_t options)" change: writecommand(ST7735_MADCTL); writedata(0xC0); to: writecommand(ST7735_MADCTL); writedata(0x80);
@@IndrekL You are the best, thanks for the help. I'm using setRotation(2), which unfortunately prevents mirroring. Do you know an easy way to fix that? (The easiest way would be to turn the camera upside down, but I'll have to re-make some parts I've built so it fits)
Nice video, very clear ! And what a performance to squeeze 10 FPS from an arduino uno !
thats the max speed you can get on Arduino uno as the max clock we can generate on gpios is 8Mhz as arduino runs at 16Mhz and fps is calculated as (pclk*5)/4000000 substituting pclk as 8Mhz we get 10fps

@@QqsMinutesaPerdre i imagine if you wire all the pin connections to the arduino into a breadboard and connect the two screens like that it should work. Did a similar thing with two different modules using the same arduino connections and it worked fine👍
Can you do it wirelessly? as in using bluetooth get the footage from camera
How can I get the image displayed on the display to move to the right or to the left (according to the amount of rotation) by turning a potentiometer left and right?
There is any way use this project with a more powerfull esp32?
THANK SO MUCH MEOWWWWW I CAN NOW SEE BETTER IN MY COSTUME !!!!!
Does this work with that orange 2.4 inch tft shield display
Not directly, because I am using a slightly modified library for the 1.8inch tft. But it probably is possible to make it work with other screens too.
Hello , plz is it possible to make image processing by Arduino on thé pictures of thé camera?
Great job! How to make a soldering microscope out of it?
You probably could use the same connections and the same code. It would be better to use WAVGAT nano instead of Atmel based Arduino since then you get 20 frames per second which is much smoother. The hardest part is to make a 3D printed body for the device and custom PCB to fit into the body.
@@IndrekL Brilliant idea to use the WAVGAT , as i have LGT8F328P sitting doing nothing, and can double the Mhz from the UNO to 32Mhz and cheaper than Nano too!. Thank you!

Nice video. Thank you for it. I have one question:
- How much time does it take to capture a photo and save it in SD card for this camera?
You should use FIFO version of the camera if you want to store the image onto an SD card. The problem is that writing to SD is too slow and Arduino doesn't have enough memory to buffer the image inside its RAM.
@@IndrekL Thank you for reply

Hey I m following your project, i m using 1.3 inch TFT display with ST7789 driver any suggestion like what should i change in your project to make it work ?
Hey! The main problem with the Adafruit's screen library was that drawPixel and even pushColor are too slow.
So I added startAddrWindow and endAddrWindow so I can just write pixel data directly to SPI without having to toggle the chip select pin between every pixel.
So you probably need to make the same modifications to the screen's library you are using.
How can I show the video output stream on a mobile application
Thank you its very excellent.
I have cmos camera how can i test it wheather its work r not
My library is for OV7670. If you have some other camera then you need to find a library specifically for that model.
Thank you very much for video
ruclips.net/video/D3U6fVxr6iE/видео.html
Hi, is it possible to connect the camera to a servo motor for tracking
Yes, you can also connect servo motors to the Arduino in addition to the camera. For example here I am using the OV7670 camera to track the black line: ruclips.net/video/HW2iLS1DyNA/видео.html
Although Arduino is very weak. You can't do very complex tracking with it.

How to send this live image from one arduino to other arduino and display the image on screen of other arduino? for wirless transmission , we using XBee module
Thanks a lot sir... For sharing this project... Just one thing... Can you make the video from the camera save to a SD card...I won't mind if you use any other board(esp..stm) for this purpose... As the Arduino might not have enough juice to control...
The main problem is that saving to SD card is slow process and Arduino doesn't have enough memory to hold the whole image before saving it.
In this case it is probably best to use OV7670 with FIFO. Then it could even be done with Arduino since FIFO saves the image quickly and then there is enough time to read it out and store on the SD card.
I will think about it. Maybe I will try it some time in the future.
@@IndrekL but can any other board be used for this purpose as stm32 or esp ...? Coz OV7670 with FIFO memory is quite costly... Anyway thanks for replying so fast...😣
The cheap STM32 "blue pill" board (stm32f103) has much more RAM than Arduino Uno/Nano (20KBytes instead of only 2KBytes) but it isn't enough to hold even one frame of 160x120x2 (2 bytes per pixel). Although maybe it is enough to buffer image while writing it to the SD card at the same time.
ESP8266 maybe if there is a model with enough IO Pins (The camera needs at least twelve - 8 for pixel data + 2 for i2c communication + vsync + pixel clock. Optionally additional 1 to generate xclck). Mabye pixel data could be written into a shift register and then read out over SPI.
If you could find a cheap SRAM chip that is big enough then even Arduino could first store it into this external SRAM chip and then later copy it over to SD card.
I am sure that there are microcontrollers that have enough internal memory but I doubt that those are cheaper than the OV7670 with FIFO camera.
@@IndrekL thanks a lot, sir😊
in arduino IDE it says file directory not found for the Adafruit_GFX.h
Can you somehow create a HUD for this?
I am going to try and make it...But I have a ILI9341display. What modifications would i have to make to the code to get it working with this display?
Hey! Getting a new display to work with it is a process. I can't just tell you how to do it since I don't know. You have to expermint with it. I had to modify the screen library to get it working since the original libary code was too slow.
Very hopeful! There is a way to send the data to PC over USB cable?
I found it on your GitHub. I'm happy now! hahaha
Hi Sir please tell me how display the picture wirelessly on such a screen
Thanks a lot Sir
Hey! I haven't done it wirelessly yet.
theoretically, at the transmitter, you could use an nRF24L01+ RF transceiver module in place of the screen since it uses the same SPI bus and, at the receiver you could connect another nRF24L01+ module to an arduino which is connected to your PC via USART to display the image data
Sopan Kotbagi Thanks a lot
@@SopanKotbagi Hey! I checked, the nRF24L01 seems to support up to 2Mb/sec data transfer. It should be doable with minimal code modification on the Arduino side, but with a lower frame rate.
is the TFT module 1.8 can be changed with the bigger TFT module than your project?
Thanks
Theoretically you can use a bigger screen, but the frame rate will drop a lot.
@@IndrekL ok, thanks👍
Hello, Indrek! Your building is cool! I want to build it own, and I have some results. My actually problem is with fps of the OV7670. I search that the fps of it, I can control with the certain types of registers inside the camera, but I do not understand how exactly do it. Can you recommend how to increase the fps of it? P.S. I tried to decrease the resolution, but it was not enough.
Are you using Arduino? With Arduino UNO/Nano the 10fps is the maximum it can handle. Otherwise clock pre-scaler parameter to change fps.
@@IndrekL Now I use the UNO to testing the camera, then I will move the stuff to the Mega to get inputs from other sensors. So, to change the fps of the camera I should change the clock pre-scaler parameter of the Arduino? If it is, then what is the range that Arduino UNO has handle the camera byte sending, because in some article I read that UNO can not handle the data with speed of 8 Mhz?
@@assylzhanizbassar1628 The maximum you can get out of Arduino is the 10fps@160x120. If you want a higher resolution then you need to lower the fps.
Indrek here I have another issue, if I will decrease the pre-scaler value to 3, then I haven't get the image. I work with resolution of 160x120, and if fps is 5 that is enough for me. But I can not get it. My purpose is to send the image to my computer through the serial port. Maybe for that I get the low fps? My PCLK 8MHz, my setting pre-scaler value is 13.
nice idea. I'm looking into doing this with esb32cam. Cheaper cam and uc in one unit. My son wants night vision, so basically this with a hefty ir flash light that is shoulder mounted or something
Man, this is a fucking help for i enter in my university!!!
I love you~~
ruclips.net/video/D3U6fVxr6iE/видео.html
How did you optimize it? I've heard that SPI and I2C are bottlenecking the live image a lot.
I compressed the sending of bytes over SPI as close together as possible. If you use Arduino library's "spi.write(data);" then it leaves huge caps between two byte.
I write directly to the SPI register;
SPDR = byte;
And then just wait until a byte is sent with
asm volatile("nop");
And then send the next byte.
@@IndrekL What about I2C/TWI?
I2C is only used for setup after start up. During the image transfer it is not used anymore.
Thank u so much sir,,, for your sharing project
Hello sir
I have an doubt that is it possible to operate 3 or 4 lens output capture only photo and send that to our gmail
Is it possible sir by using one arduino or raspberry board.
setup.h no such file or directory,how to solve it?
If I connect arduino pin to camera module without resistor then what will happen
Hello Mr.Indrek Luuk, Can the SPI data to TFT be sent by LRF24L01 type data link to make wireless capture at PC? If so, will it need 2-way communication or just one way? I need to remote capture low resolution image and send by RF data link.
I Googled the LRF24L01 and it seems to support data transfer speed up to 2Mb/sec. This is almost good enough. It could work if it is OK for you to sacrifice some resolution or frame rate. The SPI to the screen is 8Mb/sec.
For the images you only need one way communication.
Thank you I just need one image grab in lowest resolution. QCIF or QQVGA (160x120) monochrome is fine, I just need to monitor a device state that has no output.I do not mind slow transfer of 2-3 seconds per frame as I believe the 2Mb/sec is a little optimistic. I would prefer image size
This sounds reasonable. A QQVGA frame (with colors) from the camera is 160x120x2 = 38400 bytes. Getting it to work around 1fps shouldn't be too hard. Probably 2fps is not impossible (there is always overhead and timing has to be perfect)
People ask a lot about wireless transfer of the image. I just ordered a couple of LRF24L01 modules myself. When I have time I will try to do it myself also.
Hello.
Tell me, please, where to buy the components are the same as in yours the "Components" folder?
Or at least say their names.

You need to get:
1. Arduino NANO (a clone is fine)
2. This screen: www.ebay.com/itm/1-8-Inch-Mini-Serial-SPI-TFT-LCD-Module-Display-with-PCB-Adapter-ST7735B-IC/401010353521?epid=1748378921&hash=item5d5e146571:g:48EAAOSwA3dYgbyi

The red components on the component image are level shifters. But if you do it on a bread board you will be better off using resistors as simple voltage dividers. I tried to use those level shifters on bread board first but the image wasn't clear. Something produced too much noise.
Hello.
I am interested in the finished shield. (10 second in video)
Ah, ok. I designed it myself and you can't order it anywhere in assembled form.
If you download the LiveOV7670 project files from github then you can see that there is this folder:
LiveOV7670/pcb/kaamera_ja_ekraan/gerber/
If you zip the "gerber" folder then you can upload it to oshpark.com and get it manufactured. I ordered this project from OSHPark. Or you could use a Chinese manufacturer like PCBWay. Chinese manufacturers are cheaper if you want bigger or more boards.
When you receive the board you have to solder two 10k resistors and a bunch female pin headers onto it.
Excuse me, i'm from Indonesian, can this projects to see monitorring with serial monitor in arduino ide?
why you are using resistor here?
Hi!
Might sound dumb but...
Is there any way to set up multiple camera's and screens?
Hey! A single Arduino is too weak to handle multiple cameras. So you have to use one Arduino per camera.

hi..can you help me to connect ov7670 with arduino mega.. output like ash color not cleared picture..
Hey! Try checking the XCLK and Pixel clock wires. If those give bad signal then the image quality will get bad. Make sure that the connections are good and that the wires aren't too long
Sorry for the disturbance if you are facing due to my interruption but i really need it sir.
I bought OV7670 camera, but still didn't try it. Can i use Arduino mini? Powered with 3.3V and skip all that level-shifting? Will code work if i use arduino micro on 8MHz?
It should work but at half the speed. So instead of 10fps you will get 5fps.
My Arduino ide says "Specified folder/zip file does not contain a valid library
" ... I cant include the library. What I'm gonna do now?
How exactly are you trying to do the library install?
If you just copy the two library folders (Adafruit_GFX_Library and LiveOV7670Library) into Arduino/libraries folder then it doesn't give any errors.
hi again, I'm trying to mirror the screen about the y axis. From the internet I've got that I should change MY in the MADCTL register. In your code the MY bit is set: "#define MADCTL_MY 0x80".
