Robotic Arm (based on serv-arm)

Project is for education...
Arm is working with a Scratch program (that is not finished but it's still working).
Micro servos are SG90.
I use Arduino Uno card with shield Grove.

Must be connected to the computer because you need somme keybord commands.

Else, connect a second joystick to use it offline with battery...
