Found your channel recently, just tried this project and the load cell one and they both work!
Wanted to thank you for making these videos. Without you I wouldn’t have been able to make this camera work.
Keep up the great work and good luck!
Thank's a lot for the feedback!
Great stuff! Just discovered that the custom tools functionality (so ArduImageCapture) is not implemented in Arduino IDE > version 2.0. Be sure to use legacy IDE
thank you very much for sharing, I just came across this issue
thank you, I was having difficulties figuring out what was wrong
But i need to implement in Arduino IDE 2.1.1 Version. Then what I have to do. Set ArdulmageCapture plugin.
Please reply ASAP.
Which Arduino ide is suggested? 1.8.0 ?
@@nitish6491you can just go to the folder and search for a .bat file. You will see it runs some java code which is also there. It worked for me. It doesn’t need to be in arduino, you can run it outside the ide
Hi Indrek, good to see you back on these tutorials! Thank you so much for your assistance in my load cell project earlier this year. Hope to see more amazing videos from you :)
All the best,
Darren
Thanks!
For anyone who just keeps getting the red screen and everything looks correct. You even get the vsync word popping up in the terminal. Try switching out the 1k and 680k resistors for 4.7k resisters. 4.7's on both connections.
I'm not sure why this worked for me.
I believe it is a difference in the camera chip itself.
My ov767 module was labeled differently is as follows:
scl = sioc
sda = siod
mclk = xclk
pclk = pclx
vs = vsync
If yours is labeled this way it may be your resistors that need changing.
Only change the 1k and 680 though. Leave the 10k resisters alone, they are fine.
I don't know why this works I'm just documenting that it did.
Hope this helps someone, because it threw me for a loop. this guide was great though.
Also if you have the new Arduino ide It may be better to just get the old version which is still available on the website. Idk why I didn't think of that sooner trying to get this working with the new ide is annoying.
Hi, I am getting coloured blur images. Do you know what can be the issue?
@@wpprohelper9796 Did you manage to fix it?
@@user-me4ks2km3rYes, it was due to the lens. Try adjusting the lens of the camera and see if image is clear
I'm glad to have found this channel! RUclips shouldn't keep this hidden from people. 😅
Thank you very much for your video.
I can't find any information about OV7670 without FIFO in China LAN.Luckily, I found it on RUclips.Thanks again.
This is so cool! At last someone who solved the mysteries of OV7670! Idea for a future Iteration: A version that streams the Image to the LCD and into the PC at the same time. 🙂
Arduino has 3.3v output why do we have to divide the voltage with resistors
The camera is powered from the 3.3V output. The resistors are to reduce the 5V signals down to 3.3V.
@@StevenHaylesbut we don't have 5v lol. Only 3.3. What a nonsense.
I didnt watch the video yet , but the 3.3v comes from the ch340g chip which is the com chip and its pretty easy to burn this chip if you pull too much current from it. Its a better idea all in all to never use that 3.3v out and just use a 3.3v regulator instead
@@torcher5023U no need resistors on 3.3v arduinos
found your channel now and loving it man.
good day sir, i will be blunt with you. 7 years ago i repeatedly attempted to get this to work, bought a level shifter, 2 cameras and failed to make it work after many days of frustrating work.
thanks to your tutorial i have succeeded and i am extremely thankful. to be blunt, although i am not this way inclined i would be willing to offer myself to provide "favors" as i am so happy that i have managed to do this. thank you sir.
Can u give me some insight on how to achieve picture from camera
@@prajapatimanvendra3128 i can try, what are you are having issues with?
@@Project2025WILLRUINYOURLIFE I am getting that red image, insite of doing all the pixel data connections, I tried different baud rates as well.. I am using Arduino IDe 1.8.18 version
@@prajapatimanvendra3128 sorry to hear this. if you've checked your wiring is correct, make sure your resistors are correct (i find it very easy to misread the colors).
if that doesn't work, maybe check one of your wires isn't broken inside?
I've put the ArduImageCapture folder in the tools folder but I can't find the ArduImageCapture option in the tool tab in the arduina App
same, not sure why, ill let you know if i find a solution
same problem too
You could try out arduino IDE with 1.8 ver
Dude we miss you!
unfortunately not working for me. The picture where it is supposed to be green in ImageArduCapture is sometimes working, sometimes not, regardless of the baudrate. Sometimes it threws errors, sometimes not. Mostly the picture look frizzy black and green. and when noting is connected, sometimes the image is red, sometimes blue with a frizzy top.. just not working and always other seemingly random results.
How to increase fps?
Пожалуй, никак, разве что за счёт ухудшения качества и цветопередачи.
Can you please help me to install tools 😢
The video you showed us is very useful. But how make this board to send the video or photo to another device (computer) wirelessly?
I have a problem with that.
The red screen does not change .. and the vsync word appearing after the red screen appears.. i checked the wiring more than 5 times and iam sure it is right.. some times the arduino send a message that i must download the last version of arduino and imagecapture .. but arduino 2.0 does not have image capture and when i downloaded it , it does not work too.. can you help me please ❤
yup, I was doing this today and facing the same issue. Did you find any solution bro?
when downloading the code I have a problem instead of the folder LiveOV7670.ino I have LiveOV7670 which is a notepad file, but still, the type is written as an INO file can u help me with it? what should I do?
thank you,
haii, thank you sm for this tutorial, but I can't get the arduImagecapture, I have tried for many times. can you tell me how fix the problem? I use arduino ide 2.21
haiii thank you so much, finally I can connect the camera to arduino uno. then, I permit to recreate this video for my duty in the college in indonesian language🙏 hope you give the permission for it
@@nahdiafadhilaturrahma3780 hi, can I ask how you fix it?
@@KZX-nl1yh hii, what is your problem? is that the arduimage tools?
Hello lndrek, I was wondering if you knew what these boards where. My son and I are building a small robot by Thames Kosmos and I wanted to put a blue tooth camera on it. Thanks.
1. I using ov7670 camera module for obstacle Avoidance car. So I used L293d motor driver shield. How to change my own pins in the code.
2. For camera test I tried it Arduino uno without L293d motor driver shield its work.but I want to change ov7670 camera image angle.(I fixed camera which pin side below and that time image is rotated) so I want to change rotate Angele. Can you help me.
hey there can you put a video of connecting this camera to arduino
touch screen 2.4 inch display
please give library code to me
Hi Luuk, I'm looking for analyzing video data from a Camera to use it in a home made spectrophotometer, so I would know if is possible not just to display video image captured on a window, but rather logging each single video data byte from Camera to analyze it by arduino itself or eventually by PC. Thanks a lot for your any information, and congratulation for your very good explanation of all your projects. Andrea (from Rome, Italy)
Hi Indrek!
Your tutorial is amazing! Thanks a lot.
Just one question: is there any way to save to an SD card any image captured by the camera? I'm trying to do something like a "surveilance camera" (not connected to a PC): when a PIR sensor is activated, the arduino captures an image on a SD card. Is it possible? Can you help me? Thanks.
Yes its is possible, but you will require more pins and an sd card module.
Hello friend, wondering if your Arduino Spreadsheet tool works with the new Arduino IDE 2.3.2? I used to use it on older versions and it worked fantastic, but now when I put it in the same "tools" folder, I cannot see it within the IDE
same here
hey! same here, did you solve this problem? I can´t see the arduimage tool
@@anasampieri5102 I couldn’t get it to work. Hopefully he releases an update
thank you for this video but am having a bit of challenge connecting 3 different cameras and viewing them in the way you did here
Hello, very nice tutorial! Could you perhaps tell me why my image is very distorted, and you can't really make anything from it?
it keeps showing red (im using an arduino mega 2560 board and yes i wired it accordingly)
Nice! Thanks for this video. Works for me
i get the output but it's so blurry. how can I fix this?
Hey!
If it seems like optical blurriness then try to adjust the lens. You can screw it in and out.
Hi there. First of all I would like to thank you for providing such a resourceful video. I have installed the plugin and just as you said, added it in the tools folder. However I am still not able to see the option from tools bar in the arduino IDE. Would be grateful if you help.
Thankyou!
same
Idk if you still need this but the same happened to me and I had to revert to an older version of the Arduino IDE to view the option in Tools, try to get a version that is older than 2.0, 1.8 worked for me
Hi Indrek, nice project, super useful. Am planning to apply it for my final college project. Can you help creating the code to take a picture just when I tell the code to do it?
Congratulations!👍🏻
Hello!
I keep getting this error after connecting everything:
Command checksum failed!
1. Check baud rate
2. Download the latest version of the Arduino code and the image capture program
I do get the vsync after the green screen but then it turns into a repeated series of these messages. The baud rate is set at 50000 and I have downloaded the latest version from the link in the description box. All the connections are also correct
hi! i am trying this and just before checkpoint 2, the box goes orange... can you help?
Very good video!
Is there any way to adjust the contrast and/or change the colors? The contrast is way too high in grayscale mode and in RGB mode everything has a red tint for me
I tried to do everything you mentioned here but when I installed the new ide (2.0), when I installed the libraries, when I upload the code, it says this(Compilation error: BufferedCameraOV7670_QQVGA_10hz.h: No such file or directory). but in the old ide it worked! ( just to note that after the new ide was installed the old ide cannot compile for uno anymore ) but anyway because it worked in the first place, i would like to thank you for the amazing content you upload.
Thank you for the video. Will definitely try this. As an extension to this project, can you please show how to upload the images captured to google drive
Nice info, thanks for sharing it, keep it up :)
Hi, on your website "how to power an arduino", please do a VERY important addition.
You need to note that the "Arduino Nano EVERY", that exact model, should not be powered through the 5V pin.
Please add this crucial info so people dont damage their nano every.
Hey! Can you give a source for it so I can link back to the explanation of why it can't be done?
Powering it via USB will also connect 5V from the USB directly to the Arduino bypassing the VIN pin's regulator. What is the fundamental difference that makes powering it from the 5V pin damaging to the Arduino?
@@IndrekL I commented but it landed in the spam folder. Please look there
The comment isn't in the "held for review" folder. Maybe RUclips doesn't allow links in the comments at all. I selected "Always approve comments for this user" for you, which may help.
Maybe you can replace all the dots in the domain name with spaces and try again?
Thank you so much!
This helps me a lot.
I wanna ask how could I set up sepecifed path for the captured images?
Like make it automatically saved to my google drive?
Thanks again for your big help!!
Hi @indrek
i am followed your tutorials step by step, but while compiling on Arduino Uno it shows the following error message...
error: no members matching 'Adafruit_GFX::drawRGBBitmap' in 'class Adafruit_GFX'
using Adafruit_GFX::drawRGBBitmap; // Check base class first

Error compiling for board Arduino Uno.
kindly help
@rkstudio2708, if you've found the solution please share
I've solved it by removing a previously installed Adafruit gfx library
Hey, cool video, but does it also work with an ESP32 instead of an arduino? I mean do the libraries play along?
Wtf that has better quality than my camera
Hi, All was going well when I did it up until I experimented with the UART and there was an error what possibly could've happened?
Hi Indrek, thanks for the video. Please, Can I connect the D0 to D7 of the camera to I/O Expander pcf8574? Which of the camera pins are input and output? I haven't tried it because I don't want to damage any of my boards. Thank you in anticipation.
Hello, thank you for your good video. I use arduino mega in my project. When I upload the Exampleuart.cpp code to Mega, the red rectangle image does not appear; But when I use uno it appears.
Why?
Can I use your video and code on arduino mega?
Thank you for your guidance.
We had the same problem today. After looking at some other videos : The pins for the arduino mega are different from the arduino uno, here is the video I used : ruclips.net/video/8SNrivo5VDA/видео.html, in the description there is a link to github where the is the new code you should use and at the bottom of the page there are the changes you should make to your wiring.
Hope this helps
@@solalpapillard9364 thank you very much 🙏. One more question: I have searched a lot to learn how to set up this module with FIFO. But I did not find a complete tutorial that is as complete and detailed as this video. Do you know a complete tutorial for the version with FIFO?
Amazing, many thanks!!!
Hello, thank you very much for your tutorial. Do you have a similar video for the FIFO version of this module?
Hello.
Isn't there already a 3.3V pin on the Arduino Uno or Nano for the XCLK pin of the OV7670?

I can't find the ardu image file in tools. How to solve?
Hi, nicely done and super useful!
I've been trying to set up the SD card reader, even though you've specifically said it'd be a waste, just to try to see what kind of performance is possible. However, I get stuck on getting the pins to not cause collisions.
The SD card library I'm using (SdFat) wants to use hardware SPI (11,12,13), and this would be compatible with the TFT display, but D12 is used for the camera pixel clock (pclk). So long story short, I've been trying to change that pinout to D8 and move D/C to D12.
In CameraOV7670.h I found these lines (concatenated):
#include "Arduino.h"
#include "CameraOV7670Registers.h"
#define OV7670_PIXEL_CLOCK_PIN 12
#define OV7670_PIXEL_CLOCK (PINB & 0b00010000) // PIN 12
which I changed to:
#define OV7670_PIXEL_CLOCK_PIN 8
#define OV7670_PIXEL_CLOCK (PINB & 0b00000001) // PIN 12
This doesn't seem to change anything.
However, adding it to the top of "ExampleTftBufferedCameraFrame.cpp" does seem to work, but the frame just stays white and/or flickers.
Do you have any information on how to address this problem? Is it possible to change the pin for pclk to D8?
Thanks!
