Servo motor

  • Servo motors usually have 3 wires (VCC,GND,DATA)
  • No need for special controlling circuits if you have an Arduino
  • Needs a PWM signal for controlling it
  • In Arduino you can use the Servo library
  • Small servo motors will be ok to power from the Arduino 5V (max 500 mA), but it is recommended to always use an external power supply
  • Standard servo motors are usually limited to a range between 0-180 degrees, but continuous and multi-turn servos also exist
