Upload Sketch To Arduino Pro Mini Using Arduino Nano
In this post I will show you how to program or upload an Arduino sketch into Arduino Pro Mini using Arduino Nano. Maybe some of you have known that USB to Serial converter is needed to upload a sketch to Arduino Pro Mini. But if you have Arduino board previously and wanted to try Arduino Pro Mini, you dont need to buy dedicated USB to Serial Converter Board. You can use Arduino board which has integrated USB to Serial Converter like Arduino Uno and Arduino Nano.
Tools needed :
- Arduino Pro Mini
- Arduino Nano/ Arduino Uno
- Dupont Cable
- Computer which has been installed with Arduino IDE and USB to Serial driver (FTDI driver or CH340G driver)
Connect Arduino Nano to Arduino Pro Mini
Arduino Nano Arduino Pro Mini
TX---------------------->TX
RX---------------------->RX
Reset(RST)-------->GND
5V---------------------->5V
GND ----------------->GND

Next open Arduino IDE on your computer and connect Arduino Nano to USB port.
Choose the right usb port or your board on Arduino IDE, I`m running Ubuntu so it looked like below:
Choose the right Arduino board you want to program, in this case Arduino Pro Mini 5V 16Mhz w/Atmega328
To Upload Sketch
- Press and hold reset switch on Arduino Pro Mini board.
- On Arduino IDE Click Upload
- After "Uploading" appeared on Arduino IDE, release the reset switch on ArduinoPro Mini.
- Upload sketch finished.
