The servo motor provides motion control. Pulse-width modulation (PWM) is used to control the position of the motor shaft.
Internally, the servo combines a DC motor, gearbox, potentiometer and controller electronics to provide relatively precise
angular position. The servo included in the kit is a standard servo, which means it can rotate about 180 degrees. The
pinout of the servo motor includes power, ground, and the PWM signal line.
