Arduino Makefile to simplify testing and uploading Arduino sketches from the command line.

ArduinoCLI installed and in your $PATH.

Place this Makefile in your sketch directory.

export BOARD=arduino:avr:uno && export PORT=/dev/ttyACM0

or

Edit the Makefile itself and configure the BOARD and PORT options.

1. Verify code compiles: make
2. Upload to board: make upload
3. Open serial monitor: make monitor

Verify your code compiles and uploads via the ArduinoIDE. Next verify that it works with the ArduinoCLI. If it does not work with the vanilla arduino-cli it will not work with this Makefile.
