Introduction: Simple & Cheap Arduino Uno ATmega328 Programmer

Here's how to build a simple & cheap Arduino Uno ATmega328 Programmer.

Hope you enjoy it...

Step 1: Parts

Step 2: Prepare the Arduino

a. Connect the Arduino to the Computer.

b. Open the Arduino application >File >Example >ArduinoISP.

c. Upload the sketch.

d. Open Tools >Programmer >Arduino as ISP.

Step 3: Build Your ATmega328 Programmer Shield

ATmega328P Pin Mapping > Arduino

1 > 10

7 > VCC

8 > GND

9 > Crystal > Capacitor1 > GND

10 > Crystal > Capacitor2 > GND

17 > 11

18 > 12

19 > 13

20 > VCC

22 > GND

Step 4: Burn the Bootloader

a. Plug your ATmega328 Programmer Shield on the Arduino (refer to photos).

b. Plug the new ATmega328P microcontroller on the Shield.

c. Open Tools >Burn bootloader.

Step 5: Load Your Sketch to the New Microcontroller

a. Load your sketch for the microcontroller.

b. Open Sketch >Upload using programmer.

That’s it!


Thumperup made it! (author)2017-03-08

Thanks for the idea. works great

As an improvement get a ZIF socket instead. Much easier to insert and remove IC without bending any legs...

I found the flat pins of the ZIF socket permanently damaged my Arduino. You can get a ZIF with round pins here:

Why you need crystal if you program with SPI?

I use TL866A for programming Atmega with ICSP, but here don't need crystal.

Nice. This would be great for creating smaller ATmega circuits.


THIS IS "EXACTLY" what I have been looking for. Until now I have used a ST62xx microcontroller, writing "dozens" of progs. in Assambler to that. "Me, 60+ years to age" having a "new coming" in pros. world with Arduino. Can you imagine how hard it has been to find out how to prog. a "clear" ATmega? Now I got it. It kind of a "snapped" in my head after reading Your instruct. Thank YOU. I propably make an Instructable of creating a PCB on this, (propably there allready exist somewhere a one like it, but I haven't found 1 yet)

This is probably the most rewarding comment an instructabler can hope for. Thanks a lot!
Check this out for a "pro" version and the PCB design.

Well I am 62 and I to am looking for answers to building a robot from a Jazzy mobility chair. Tell me at our age how did you find the key to unlock that vault. I would really like to know :-)
