It is very easy to control servos with the help of the Servo Library which is part of Arduino. For my tests I was using an evaluate the following small Servos:

I wanted to investigate the expected power consumption. For this I used the Sweep Example from Arduino.

Power Consumption at 5 V

  • 1.5g Servo: N/A
  • 1.7g Servo:  0.05 A (max 0.1 A)
  • 3.7g Servo: 0.05 A (max 0.06 A)

It seems that the 1.5g Servos were damaged and did hardly move: they were getting very hot and consumed up to 0.9A
