range. The default is 180 degrees but your servo may have a smaller sweep. You can change the total angle by setting

actuation_range .

For example, to set the actuation range to 160 degrees:

Often the range an individual servo recognises varies a bit from other servos. If the servo didn't sweep the full

expected range, then try adjusting the minimum and maximum pulse widths using set_pulse_width_range(min_pulse,

max_pulse) .

To set the pulse width range to a minimum of 1000 and a maximum of 2000:

That's all there is to controlling standard servos with the PWM/Servo HAT or Bonnet, Python and ServoKit !

Continuous Rotation Servos

To control a continuous rotation servo, you must specify the channel the servo is on. Then you can control movement

using throttle .

For example, to start the continuous rotation servo connected to channel 1 to full throttle forwards:

To start the continuous rotation servo connected to channel 1 to full reverse throttle:

To set half throttle, use a decimal:

And, to stop continuous rotation servo movement set throttle to 0 :

That's all there is to controlling continuous rotation servos with the PWM/Servo HAT or Bonnet, Python and ServoKit !
