#Explorer HAT Pro, Motors, Servos and Steppers

Find this Gist at: tiny.cc/explorerhat

The Motor driver on Explorer HAT Pro can not only drive motors, but a stepper motor too. And just like the Pibrella the outputs can also drive a motor or four, or another stepper.

Explorer HATs outputs sink to ground, meaning that you need to connect whatever you're driving between 5V and the output

#MOTORS

import explorerhat
import signal

def toggle_output(channel, event):
    print("Got {} on channel {}".format(event, channel))
    if channel < 5:
        explorerhat.light[channel-1].write(event=='press')
        explorerhat.output[channel-1].write(event=='press')
        
explorerhat.touch.pressed(toggle_output)
