Arduino Continuous Rotation Servo
These are Arduino continuous rotation micro servos are the same ones that we use in the LittleBot to drive its wheels. They are controlled with a PWM signal just as you would control a standard servo. But instead of controlling the position of the servo the PWM signal controls the speed as shown below.
- PWM = 180 - Full Forward
- PWM = 90 - No Movement
- PWM = 0 - Backwar
