Chapter 10, Using Python to Control Servo Motors

• What does the acronym PWM stand for?
  • Pulse Width Modulation: the means of controlling a device by varying the size (or width in time) of pulses sent to the device
• In terms of the Servo motor's internal mechanism, from what components is the error calculated?
  
  • The difference between the actual current position of the motor and the requested position of the motor
• What is a servo "horn"?
  • A small collar with arms to attach to a servo motor spindle to convert its output into motion
• What could result from a servo being impeded when trying to reach a requested position?
  • It can lead to overheating and damage to the servo motor.
