Classes

class MotorBidirectional (pin1_num, pin2_num, direction=1, running=False)

Motor DC rotates in one or the other direction with current, it can be inverted, it's basically mandatory to use a H-Bridge, a pin (0,04 A) doesn't have enough Ampere to move a motor

constructor. :param pin1_num: number of pin that will give power or be ground :param pin2_num: number of pin that will give power or be ground :param direction: which pin should give current, can be 1 or 2 :param running: the initial condition of the motor
