Arduino Command Line Usage

arduino is simply a program from your installation directory. Without any parameters, it would just start the Arduino IDE.

open ~/.bashrc and add the following line at the bottom:

              PATH=$PATH:/home/aaa/xxx/yyy/arduinoIDE/arduino-1.8.2

Now we can use cmd "arduino" everywhere.

Use cases:

For arduino nano:

arduino --board arduino:avr:nano:cpu=atmega328 --port /dev/ttyUSB0 --upload beep.ino

Serial Monitor:
picocom /dev/ttyUSB0 -b 9600
