User Manual

DC motors are controlled by 4 PWM output pins, the 4 PWM pins let you control speed

and

direction. And we'll use our

adafruit_motor library to help us manage the throttle (speed) and direction for us, making it very easy to control motors

Note that each DC motor is a little different, so just because you have two at the same throttle does not mean they'll

rotate at the

exact

same speed! Some tweaking may be required

Import Libraries

We start by importing the libraries that we need to have time delays ( import time ) and then the main crickit python

library that will make it super easy to talk to the motors and sensors on crickit ( from adafruit_crickit import crickit )

The crickit object represents the motors and servos available for control. The motors are available on the sub-objects

named dc_motor_1 and dc_motor_2

The two wires of the DC motor can be plugged in either way into each Crickit Motor port. If the motor spins

the opposite way from what you want to call 'forward', just flip the wires!



import time

from adafruit_crickit import crickit

print("Dual motor demo!")

# make two variables for the motors to make code shorter to type

motor_1 = crickit.dc_motor_1

motor_2 = crickit.dc_motor_2

while True:

motor_1.throttle = 1 # full speed forward

motor_2.throttle = -1 # full speed backward

time.sleep(1)

motor_1.throttle = 0.5 # half speed forward

motor_2.throttle = -0.5 # half speed backward

time.sleep(1)

motor_1.throttle = 0 # stopped

motor_2.throttle = 0 # also stopped

time.sleep(1)

motor_1.throttle = -0.5 # half speed backward

motor_2.throttle = 0.5 # half speed forward

time.sleep(1)

motor_1.throttle = -1 # full speed backward

motor_2.throttle = 1 # full speed forward

time.sleep(1)

motor_1.throttle = 0 # stopped

motor_2.throttle = 0 # also stopped

time.sleep(0.5)

# and repeat!
