Continuous Rotation Servos

If you're using continuous servos, you can use the angle assignments and just remember that 0 is rotating one way, 90

is 'stopped' and 180 and rotating the other way. Or, better yet, you can use the crickit.continuous_servo_1 object

instead of the plain servo_1

Again, you get up to 4 servos. You can mix 'plain' and 'continuous' servos

If your continuous servo doesn't stop once the loop is finished you may need to tune the min_pulse and max_pulse

timings so that the center makes the servo stop. Or check if the servo has a center-adjustment screw you can tweak.

Disconnecting Servos or Custom Pulses

If you want to 'disconnect' the Servo by sending it 0-length pulses, you can do that by 'reaching in' and adjusting the

underlying PWM duty cycle with:

crickit.servo_1._pwm_out.duty_cycle = 0

crickit.servo_1._pwm_out.fraction = 0

import time

from adafruit_crickit import crickit

print("1 Servo demo with custom pulse widths!")

crickit.servo_1.set_pulse_width_range(min_pulse=500, max_pulse=2500)

while True:

print("Moving servo #1")

crickit.servo_1.angle = 0 # right

time.sleep(1)

crickit.servo_1.angle = 180 # left

time.sleep(1)

import time

from adafruit_crickit import crickit

print("1 Continuous Servo demo!")

while True:

crickit.continuous_servo_1.throttle = 1.0 # Forwards

time.sleep(2)

crickit.continuous_servo_1.throttle = 0.5 # Forwards halfspeed

time.sleep(2)

crickit.continuous_servo_1.throttle = 0 # Stop

time.sleep(2)

crickit.continuous_servo_1.throttle = -0.5 # Backwards halfspeed

time.sleep(2)

crickit.continuous_servo_1.throttle = -1 # Forwards

time.sleep(2)

crickit.continuous_servo_1.throttle = 0 # Stop

time.sleep(2)
