# A Makefile for Arduino Sketches This is a very simple Makefile which knows how to build Arduino sketches. Until March 2012, this was simply posted on my website where you can still find [what documentation](http://mjo.tc/atelier/2009/02/arduino-cli.html "Documentation") exists. If you're using Debian or Ubuntu, you can find this in the arduino-core package. ## Commands ### Serial Monitor If you have minicom installed, you can run `make monitor` to open the serial output. You can use a different serial monitoring tool (e.g. screen) by overriding the `SERIAL_MONITOR_BINARY` and `SERIAL_MONITOR_FLAGS` variables.
