Stepper Motor Control Service

Today I have been busy developing a stepper motor service class. The service class will allow the Team Seaford robot to play crazy golf. import RPi.GPIO as GPIO import time class ServiceStepMotor: PinPhase1 = 14 PinPhase2 = 15 PinPhase3 = 17 PinPhase4 = 16 Steps = [ [1,0,0,0], [1,1,0,0], [0,1,0,0], [0,1,1,0], [0,0,1,0], [0,0,1,1], [0,0,0,1], [1,0,0,1] […]

In this example, […]
