In this video you will learn how to use the Arduino ATMEGA328 microcontroller chip as a stand-alone microcontroller. I got mine here:
s.click.aliexpr...
And the dip socket here:
s.click.aliexpr...
They cost only 2 bucks, can do the same as your Arduino and make your projects extremely small.
We will cover the pin layout, how to make it ready for the Arduino software by burning a bootloader and how to upload sketches.
Watch the rest of this video to find out how you can make your Arduino projects smaller and cheaper in no time.
Parts list
1 Arduino
1 ATMEGA328P-PU chip.
Breadboard
Wires
Optional: LED and 330 ohm resistor for testing
Download and install library
An Arduino board comes standard with a 16MHz external oscillator.
We don't really need this 16MHz oscillator as the ATMEGA328P-PU has a 8MHz oscillator build in.
In order to make this chip work as a stand-alone microcontroller at 8MHz, we have to download and install a library for our Arduino environment.
To do this, click the link that match your Arduino version to download the zip file.
It will be eater
1-6-x.zip
www.arduino.cc...
1-5-x.zip
www.arduino.cc...
1-0-x.zip
www.arduino.cc...
Next we have to find the Arduino sketchbook folder by clicking on File → preferences → “Sketchbook Location”. In my case “C:\Users\tomtomheylen\Documents\Arduino” this can be different in your case.
Copy the location and go to “this pc”, paste it in the bar and press enter.
If you see a folder named “hardware”, open it.
If not, make a new folder named “hardware” by right clicking and select “new → folder” and type “hardware”. Now open it.
Move the breadboard folder from the zip archive to the “hardware” folder.
Restart your Arduino IDE and go to “Tools → board”.
If everything is OK, you should see in the list “Atmega 328 on a breadboard (8MHz internal clock)”.
The most difficult part is done now so let's have some fun pumping life in that ATMEGA328.
Burn bootloader
These ATMEGA328 microcontroller chips usually come empty. To make them work with the Arduino IDE, we have to do something what's called “burning a bootloader”. It is a tiny bit of code we burn on the chip so it will understand the Arduino software.
To do this, connect your Arduino to your computer and go to “File → examples → ArduinoIsp” and select “Arduino Isp”. Upload this sketch to your Arduino and disconnect from your computer.
Next we connect the Arduino with the ATMEGA328 as you can see in the image.
Note the half circle on the chip. Make sure it is on the correct side.
Now connect your Arduino and in the Arduino IDE go to “tools → Programmer” and select “Arduino as ISP”.
Next go to “Tools → Board” and select “Atmega 328 on a breadboard (8MHz internal clock)”.
Now go to tools and select “Burn Bootloader”.
Your bootloader is burned and your chip is ready to upload sketches!
In case you have an error message, unplug your Arduino and repeat the previous steps.
Uploading sketches
To upload a sketch you have to remove the ATMEGA328 chip from the Arduino board and connect to the breadboard as shown in the image.
I have connected a led with resistor on the board to test the blink sketch.
Here is how to use this image for the pin layout.
So for example if you initialize pin 13 in the IDE, it represents pin 13 on the Arduino board or pin 19 on the ATMEGA328 chip.
Congratulations, you made it! You can now start soldering your own minified Arduino projects for next to nothing.
A few helpful tips
I will end this video by giving you a few more more helpful tips:
If you solder a project, you need to use a 28 pin DIP socket and add the ATMEGA328 after soldering the project.
I got mine here:
www.banggood.co...
It is good practice to solder some male or female header pins to the 3 first legs so you can still change or upload sketches if needed.
If your micro controller is behaving weird, you can add a 10 to100 uf capacitor in between + and -.
Make sure when you order the chip that it is the ATMEGA328P-PU.

Finally someone who explains it step by step. Thank you!
You are right
I came back to like the video. I had watched this 7 years ago when I was first getting into school for computer science. I had purchased some atmega 328 chips but needed further education to begin really digging in and enjoying what I could do with them. I’ll admit I’m no electrical engineer. But I enjoy the puzzle of logic
Your guides are always great! If only a 1.8 library existed
i think the 1.6 shoudl still work
@@MaxDiscere So you could use 1.6 file with 1.8.x version?
@@ianthehunter3532 yah
I had 5 blank chips. Could not program them. After this video, i could burn a bootlader to them. Thanks a lot! God bless ya!! 😊👍✌👏
were these atmega328 or atmega328P
Atmega328P-PU. Try out Nick Gammons bootloader burning method via serial monitor. Easier too.
im doing the same tutorial lol
@@ezeprojects5425 What's the big difference?
Great video -- this is exactly how an instructable should be done: clear instructions and easy to follow -- you've just gained a subscriber! I'm going to order some Atmega chips for use in my production versions of my projects (rather than using the larger, more expensive Arduino boards)
Hi, Great the video has helped you. I use also very often the nano because they are cheap and small like this one here. Have a great day.

@@TomHeylen1 I'm going as small and cheap as possible, bypassing breadboards for production -- considering the AtTiny instead, soldering the wires on
Already done this on my projects and all worked 100% THANKS!
Good to hear. Cheers.
Love the Kite-board in the background. Thanks for the great video. Good Winds to you.
You are the first one to notice. Great! The board in the back is a wakeboard but kiteboarding is what I do. Wakeboarding when there is no wind. The last few years mainly hydrofoiling. Cheers and have a great day!
finally. someone who explains how to do this properly. theres lots of other videos online but they slightly mention 'oh yeah also hook up an external clock' i mean cmon.
For all of you with an error when burning the bootloader:
Try to connect a 16MHZ clock between the pins 9 and 10 of the atmega328p chip. Now connect pin 9 and 10 to GND using a 22 pFarad capacitor (with pin 9/10 I don't mean the digital Pins, but the pins you can find on the pinout). Should work now!
Simpel, brief and straight forward and very effective explanation. 👍
😀His explanation is best... 😀👍.. Simple and straightforward.... 👍
this worked for me under 1.8.4. (file in breadboard folder: 1-6-something) however there was an error about efuse, which another guide suggested to ignore. That was good advice so far.
- If you continue to program your atmega using ftdi (next video) you also preserve your bootloader and this worked well for me
- make sure to turn on verbose uploading in Preferences, to have any clue as to what's going on!!
Just FYI - the 16MHz crystal you are pointing at is the one for the Atmega16U2 chip used for USB ;)
The Atmega328 crystal is a resonator, the tiny gray thing just above the chip.
Thanks for this information. finally you explain very easily step by step. i done it. again thanks for this...............
Great tutorial, you explain things very well. I particularly like the header pins for reprogramming, sure saves time!
Would it work if I put this burned chip instead of the original atmega328 if it broke or something?
Great, thanks so much for your video
I've successfully moved my main project from Arduino to an ATmega328p on a custom PCB (mostly thanks to your video), but now the EEPROM values I used to save when using the Arduino are no longer getting saved or retrieved. I can't seem to find any info online on how to modify the code to use the EEPROM on the standalone ATmega. You seem to know so much about this stuff, I'd owe you one if you happened to have insight on this!
I am guessing the Arduino always has to be connected. (which is why i rather do old School electronics. I also assumed You can just program the chip then just use Your own board with no Arduino connected
@Christian Weissmuller Hi yes it took me a long while to understand that,
Thank You
Great video!
this was made for me i think..thanks a lot..but i'm going to use HC-05 Bluetooth module with this standalone uno, will it work?
You are inspiring me into making a "Liberating an ATmega with a Raspberry Pi vid! Hehe. Have you tried making a v-usb USBasp bootloader? This way, you can upload sketches, and even debug, through a USB cable, with only passive circuitry, and 5 inexpensive components ... and ... well, you'll need a crystal, which is also inexpensive.
I haven't done that yet. I'm experimenting with the Onion a bit lately.
Subbed. As novice you explain things very well I am going to give this a try. looking into getting a arduino very soon thanks for uploading the video
Thanks brother..
Nice job. Have you stopped uploading videos. Go on, please. Keep it up
Very informative man
It's very cool because you can use the ATMEGA328 with 3.3v, to upload sketch use 5V, be careful with the 3.3v sensor connected. Before upload sketch disconnect it.
Hi Tom,
I have an Atmega328 with a bootloader already burned.
Also, My arduino IDE version is 1.8.5
Will the 1.6 zip file still work?
Did it?
i have the same question. if anybody has tried it can they please answer
Where can we download the images from the video? They would be a great guide to hang on the wall of the workshop!
Thanks for the great video. So far, it's my favorite way to do this!
project work for me!! Thank you very much. Is there a download for atmega328p-AU to use 8mhz so it can be standalone on breadboard?
in this case, the Arduino uses a resonator instead of crystal as you can see on 1:05 above the chip, the crystal that you showed does not belong to the atmega328
thank you very much for useful video, but i have a little problem, when i try to use push button, when i press it everything get restarted, should Capacitor resolve this problem?
FANTASTIC
What if we have an arduino uno where you can't remove the IC? Is there any way to upload sketches to the atmega328? I have one that already has the bootloader but I don't have a USB to serial cable. Is it possible to cut up a USB cable and attach to breadboard? Please help!
Watch my video on ftdi connector. I think it will solve your problem. Have a good one. Cheers
Does this process eliminate the delay of booting time?
Thank you for the guide. I'm getting this error:
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
Any idea?
I had same. Then I realized I had chip backwards. Then I checked wires again, but inbetween checking and programming one cable came loose, it worked when I connected everything properly. These tiny wires can look like they are connected when they are not... Nick Gammon's sketches also helped to do tests.
In my case the oscillator it was broken. but i think it show the same error when the micro (the atmega) is not in reset mode, i mean when you reset it but you take too much time to upload the sketch. Hope it help. If is there any thing i can do for you just let me know. Regards
Is there also a tutorial available which shows the same with an atmega32u4? I need a standalone arduino which supports USB serial communication and I really can't find any good tutorial on that..
a lot of other tutorials ive looked at say to connect two .1mF capacitors between pins 7 and 8, 20 and 22. Are those needed? It doesn't look like you had any in this
Thank you for the video. Is it possible to use the ATMEGA 328 with Raspberry Pi projects?
Thank, it very helpful
hi can i use a SMT atmega328 and just match the pinouts to this?
Will this method work for a generic version of arduiono? One that does not have a chipset? I assume that it can but that I will not be able to test on the arduino.
I have one question .....I want to use Bluetooth modules in atmega 328p(without external crystal).would it work??
Thanks very much Tom
I am begginer, looking for simple solutions. If I buy a controller with bootloader on it, can I just replace the original to programme it? (On arduino uno directly)
You will probably need a serial to USB adapter
Very Well done Tom!! ... Thank You !! ... I liked and Subbed.
At 4:08, there was a wrong in the sketch (diagram), the RESET pin of ATMEGA328P-PU shall be connected to RESET pin (not to pin 1) of Arduino UNO , if you connected as in this video you will not be able to re upload a new sketch again
Thanks for sharing. Now it works. Too bad that Tom doesn''t mention this somewhere - or in other words, has errors in his video :-(
Anyway - I'm glad that he did this video & you corrected it! Thanks dudes!
hi sir we have at mega 328p programmed chip( chip is 4x4 ) and we want to
take a backup from this chip.please tell me how to take a backup from this chip?
when can we use a Universal programmer to take a backup from this chip?

You can't make a backup of this ship. This is called intellectual property. You don't have the source code, you can't do anything.
thak you sir
Would I be able to do this also with the 328P 32-leg square chip if I bought the socket for the chip, since its SMD type component? (Arduino Nano)
The 16Mhz Crystal on the UNO only gives its pulse to the small microcontroller, that handles the USB connection - The Atmega328 is clocked by another ceramic oscillator!
I see two crystals onboard.
@@a.bax.5992 Are you sure about that? If so you must have a very rare clone.
Almost all Unos and Megas and the clones have a crystal for the usb connection and ceramic resonator (which is not a crystal) for clocking the main microcontroller. - crystals usually are accurate to within 100ppm which is nessesary for the USB communication, where as ceramic resonators are only "accurate" to within 3000-6000 ppm, which becomes really noticible, when you are trying to control timing sensitive applications with it.
I tried to build a telescope tracking system, and it was really off, after only a few seconds... the ceramic resonator on my Uno is 1500ppm too slow... After using a sqrw signal from a RTC module for timing it works great. (the crystal in the RTC is accurate to within 6ppm and temperature corrected).
at 3:22 u say to put the chip on the breadboard but later when u say to burn the bootloader u remove the chip from the arduino board. do we burn the bootloader when the chip is on the arduino board or the breadboard?
Burn the bootloader when it's on the breadboard. Let me know if any issues
Thanks that was so helpful
Hey Tom, have you ever tried setting the fuses to let you use PB6 and PB7 (the oscillator pins) as digital IO ? I know it's possible but I'm not sure how that will work out with the arduino pin numbering.
When I want to use a crystal, do I need to do anything different, or can I just add it to the breadboard?
Can I use the original chip of the arduino uno even I did not burn the bootloader to shrink my projects? Thanks!
Sure you can
@@TomHeylen1 Thanks idol
I had to copy the library to the hardware folder of the installation folder of the Arduino IDE. I am using UBUNTU 18.04 LTS and Arduino IDE 1.8.12. In my case this was /opt/arduino-1.8.12/hardware
What's the difference between ATmega 328, ATmega 328P and ATmega 328P-PU?
Thanks for the tutorial! Is it possible to just download the sketch when the chip is still on the arduino and then just take it off and then put it on the breadboard for your project- without all the wiring ? --And then just stick a new chip back on the arduino so you could do it again for multiple projects? thank you
I would recommend you to build some circuit where you have 2 ends, one for the arduino and another one for your ATMEGA328 , so you just leave it there ready to plug
Nice video
Very Cool; very well done!
I assume this is not possible to do with a One SMD, right?
You have a nice Australian accent.
Very nice!
What if I have a version of the arduino where a I can't remove the uC, how do I upload sketches
Did you ever figure this out? Because I have the same problem as you.

even ii hab the same problem
did you install the bootloader and do you have the right driver for the usb to serial adapter.
Does not longer work. While uploading the bootloader it gives me this error:

I am using: IDE 1.8.9
and: breadboard-1-6-x
i have an atmega 328 chip that i have already programed.. how do i use that as a stand alone?
so bootloader is like an operating system and a 'sketch' is the program?
What are the max current input I can give at 5v and 3.3 v to power it not for use in pins
Why does the Arduino Uno board have a 8Mhz crystal, if the Atmega 328P has an internal oscillator ?
Love this for the atmega328p-pu. Does anyone know if this works on atmega328p-au?
So if we remove all jumper wires instead of wires which are providing power and gnd to the atmega then the atmega should work right?
No. Just buy a goddamn bms
@@muhammadwaqar3406 cant do that. My director wont allow me
Great job! Thanks for your guide =)
Tom Heylen
Will your procedure for BootLoading the Atmega328P-PU work using an Arduino UNO CLONE, made in China, operating on CH340 USB driver?
Thanks for the advice.
martymarty
Yes
Will a ATMEGA328-PU work? What he said had an extra P.
My friend nice video but, the 16 mhz crystal you show us is not the arduino crystal is the 16 mhz crystal for the usb circuit , the 16 mhz arduino crystal is the very small crystal near to pin 10 on the board
well done sir.
I have made a project with Atmega328p .
The project is an 1HP motor(water pump) control .
the circuit have sonar sensor ,16*2 LCD, relay,ULN2003,7805, crystal, capacitors, 10k variable resistor .,...it is working properly with 9V HW battery ,but when I am trying it with 12V adopter(adopter is ok- also tried with two more adopter) its not working....what would be the cause....My english is not good .....please reply
Very likely that the adapter does not have enough amps. Check the amps your circuit uses and compare it with the adapter. Have a good day!
+Tom Heylen thank you sir....
Sir my arduino uno has non removable Atmega Chip. what should I do to burn an external atmega?
Does this work for Arduino 1.8? Do you have the download?
Like in all videos: it is never mentionned what is the true reference you burn on the breadbord.
Yours is a P - PU but there are Atmega328 without P or with PU without - before.
I'd like tu burn these types for myself : i have a signature problèm. I change for what it should be but i did not check wath the signature really is. Unfortunatly i cannot have any accès to the chip except may be with another protocol as i saw.
Did not really use your method but the one that connects pins 10 11 12 of the chip.
that electrolytic capacitor you used ?
thanks very useful
If I use the web version of Arduino create - which zip file do I need?
Sometimes there is no need to do whole this process (burning the bootloader) on such chips ( "PU" in the description) because many of them have already the bootloader burnt on them. So, pay attention when you buy.
i am using bootloader programmer but i am not aware of steps and connections..can someone help to proceed further.
But a Nano is just $2, I’ll consider this if I were to embed my project into a small package but I’ll probably use one of the 8 pin chips
can i use arduino nano in place of uno
I have atmega328-pu, its not working . ( Error while burning bootloader.) Help me
Awesome!! I just got 2 micro controllers like those... hehehe also I have a couple of arduino pri mini, I guess I should have no trouble, firmware is basically the same. I will let you know any news!
OMG awesome Awesome ............ Finally you won over me !
If I don't want use arduino as power supply, did I need use voltage regulator in this arduino circuit?
Yes, and no. Depends on the application, and on decisions about 5V or 3,3V peripherals, if you intend to use the ADC (Analogue Pins). Generally having a proper regulated supply and over voltage, excess current and reverse polarity protection is always worth it. Some varieties of the ATMEGA328 will operate at a wide range of voltages (about 1.8 to 5.5V) but not all sensors etc will be as forgiving.
In the Version 1.6.9 com the warning: "Warning: Board breadboard:avr:atmega328bb doesn't define a 'build.board' preference. Auto-set to: AVR_ATMEGA328BB" and it takes a long time to compile.
May it be, that I need an older Version of Arduino Compiler?
I have the same problem...
did you solve?
Likewise - same problem (I'm running Arduino IDE v1.8.19. Anyone know of a solution?
Oh I found the problem. He has the sequence incorrect. This error occurs when you set 'ATMega328 on a breadboard...' as the board before you upload the ArduinoISP sketch - you need to select your Arduino Uno board first, then upload the ArduinoISP example to it, then do the wiring to the breadboard Atmega328 chip, then select 'ATMega328 on breadboard...' the follow instructions to burn bootloader (3:29).

Did the atmega328 came from the arduino ?
@@JS7457 I bought them from ebay, they are ATMEGA328P U. I tried programming the bootloader using the UNO as SPI and the atmega with 16 mhz crystal attached and selecting Arduino Uno in boards(16mhz) and it works perfect.

Check your connections. Be careful as there is two VCC and GND on the atmega, connect them together.

specify which type of chip to use! your using a "atmel 1417" atmega 328 means nothing! their are possibly 3 serial numbers on each chip. some only have 2. "atmega 238p-pu" is one but their are many types some are not even rectangular some are square chips! their are lots of "ATMEL" all are atmega328. however, you do specify which one to use in your down load. i think do you have the exact right type?
