I am not used to talk in English ‍

There is not a lot of information about Arduino Mega 2560 and how to use it with GRBL on YouTube, so I thought I had to make a video about it, I hope you guys learned something new.

The gena github library

I used the Universal Gcode Platform 2.0.11 to communicate with GRBL Firmware, of course you don't necessarily have to use it.
