+ | They have one really great feature: the interface to control them is super simple, just the pulse width of a digital pulse sent to the motor at a rate from 50-200Hz. The pulse rate is not that important. The important thing is the pulse width. The range of the pulse width is from 1-2ms. 1.5ms is the middle servo position and 1 or 2 ms are the end positions. | ||

+ | The wiring of servo motors is also simple: 3 wires consisting of power, ground, and signal - see below. The input signal is a positive digital pulse of at least 2V. The power supply can range from 4V to 7V. Even higher voltages can be used but may burn out the servo if it stalls. The higher the voltage, the faster the servo. | ||
