The DC.clockwise() and DC.anticlockwise() methods can take optional parameters to extend their functionality



The duration parameter can be used to make the motor spin for a number of seconds. For example, use motor.clockwise(duration=3) to make a motor (DC object named motor) spin clockwise for 3 seconds.


If the duration parameter is being used to make the motor spin for a number of seconds, the wait parameter can be used


The speed parameter can be used to control how fast the motor spins using PWM (Pulse Width Modulation).

speed can be either a tuple or an integer. When using a tuple, order matters and it should be (frequency, duty_cycle).

There is also the option to be explict and use the l293d.PWM namedtuple which takes the 2 keyword arguments: l293d.PWM(freq=x, cycle=x).

PWM examples

import l293d

motor = l293d.DC(22, 18, 16)

# pre-define a pwm
pwm = l293d.PWM(freq=30, cycle=70)

# or use it directly in the method call
motor.clockwise(speed=l293d.PWM(freq=50, cycle=50))

# keywords aren't required
motor.clockwise(speed=l293d.PWM(50, 50))

# normal tuples work too
motor.clockwise(speed=(20, 30))

# an integer can be used if you want the same frequency and duty cycle

Implementation Examples

import l293d
motor = l293d.DC(15, 18, 11)

Turns motor on in the clockwise direction. Doesn't stop until motor.stop() is called

As duration is the first parameter of the anticlockwise and clockwise methods, the line above would make motor spin for 3.5 seconds before the method returns

motor spins for 7 seconds, but the method returns immediately. This means that any code following this line won't be delayed.
