Arduino: Servo

Used a Vex 3 wire servo from VexRobotics. I used a small example code for Arduino called Sweep to see how far the servo can turn. I was happy to find out that it can do 180 degree instead of 100 degree.

(From Vex Robotics)

  • Rotation:100 degrees
  • Stall Torque:6.5 in-lbs
  • Voltage:4.4 – 9.1 Volts (Motor life will be reduced operating outside this range)
  • PWM Input:1ms – 2ms will give full reverse to full forward, 1.5ms is neutral
  • Black Wire:Ground
  • Orange Wire:Power
  • White Wire:PWM signal
  • Current Draw:20mA to 1.5 A per Servo
