By

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

Hope you enjoy it...

Step 1: Parts

Computer.

Arduino UNO.

Perfboard.

PCB connectors pin header.

ATmega328P microcontroller without bootloader.

28 pins socket.

16MHz crystal.

2x 22J capacitor.

Wire.

Soldering kit.

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!
