H-Bridge adaption for GRBL #1868

[Info]

Hi, I wrote an Arduino sketch implementing a simple and cheap H-Bridge adaption for GRBL. The original idea was to flash it to an ATTiny85 but it should run on any controller or development board adapted to the Arduino Core.

It offers soft start, soft stop and soft transition for the spindle motor by dragging changes of the PWM duty of the Spindle Enable pin. It also offers seperated pins for spindle direction control.
