Program Arduino Nano via Uno with ICSP

Hello Friends,

            In this tutorial, I have shown that how can you program Nano via Uno. As you can see in the above image, my Arduino Nano's USB female pin is broken. So I have to find a way to upload the sketch to it some way. One day I was Google-ing, I have read somewhere that an Arduino board can also be programmed via another Arduino board. 

Tools you will Need :

1. Arduino Uno ( which will act as a programmer ).
2. Arduino Nano ( to be programmed ).
3. Jumper Cables ( Some male-male, male to female )
4. Breadboard

Step 1: Preparing programmer

             Attach your Arduino Uno to PC. & go to File > Examples > ArduinoISP > ArduinoISP. 

A sketch will open, upload it on Uno. When uploading is done. unplug it from the PC. Now, Attach Uno & the board you want to program with jumper cables just like the image below.

In the above image, you can see a small (1) or (*) or (.) is marked near the ICSP headers, that is the 1st pin of ICSP headers.

• D13 to SCK, 
• D12 to MISO, 
• D11 to MOSI, 
• D10 to RST, 
• 5V to VIN
• GND to GND
  

Note: If your board's operating voltage is 3.3V then use 3.3V instead of 5V.

Step 2: Preparing Arduino IDE

                

            All wiring is done. now we have to do some settings in IDE.

• Go to Tools > Board & select Arduino Nano.

• In Processor, select ATmega328.

• & In Programmer, select Arduino as ISP. ("Arduino as ISP" not "ArduinoISP")

The settings is done.

• Now, open up the sketch you want to upload on your Nano,
• In Menu, go to Sketch & click on "Upload using Programmer"

IDE will compile the sketch & upload it to your Nano. The RX TX LEDs will blink rapidly on both boards, & you will see done uploading.

If not, then recheck all the wiring & settings.

If you get any problems or you want to give me suggestions, you can write in the comment section below.

Happy Programming ^_^


Thank You.
