I’ve just put together the STS-Pi using a pi zero and explorer pHAT , which is the first time that I’ve tried controlling motors with a pi.
Everything working, except for one of the motor controls (Motor 1) on the Explorer pHAT. I can only get it to turn one way.
The “ eh.motor.one.forwards” command doesn’t seem to have any effect, whilst “eh.motor.one.backwards”is fine. I’ve double checked my soldering and the connections look fine (checking BCM19 and BCM20 in particular - does one control forward and one back?).
Any suggestions on what could be the problem? Is there a way to check that the pins on the explorer pHAT are working as they should?
