Arduino mega XV-11 LDS motor dirver test

I make a adapter using Arduino mega 1280 to output PWM to control XV-11 LDS motor.
LDS motor power directly from USB 5V with a IPS041L low side switch control with PWM.
The XV-11 LDS data is connect to Arduino mega RX3 then relay senf out from TX ( USB-serial ).
So the user can use Xevel's program to see the lidar plot. [update] Currently it is has simple close loop control. Arduino mega code you can get from here( github).
