It executes the basic functions, such as:
-Displaying the status of the machine
-Move the axes
-Auto Home ($H)
-Unlock grbl ($X)
-Make position 0 (G92 on all axes)
-Read a MicroSD and send the commands to the machine
-Modify in real time the speed of movement of the machine
-Modify in real time the spindle RPM
-Among other options that will be added

Components:
-Arduino Mega
-Rotary encoder

The file to compile from Arduino IDE, is in the folder LCD_GRBL/src/Codigo.ino

If you want to work from VSCode and PlatformIO, import the folder containing
the platformio.ini file. This folder already has the necessary libraries for the
operation of the project, so it will not be necessary to download them.
