This servo rotates fully forward or backward instead of moving to a position. You can use any servo code, hardware or library to control these servos. Good for making simple moving robots. Comes with four different horns.
To control with an Arduino, I suggest connecting the control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE. Position “90” (1.5ms pulse) is stopped, “180” (2ms pulse) is full speed forward, “0” (1ms pulse) is full speed backward.
