Standard Metal Servo (MG946R)

It is upgraded version of TowerPro MG945 with the new PCB and IC control system which makes it  more accurate. Its internal gearing and motor are also upgraded to improve dead bandwidth and centering. This high-torque standard servo now comes in a metal-gear flavor for extra-high torque (13 kg-cm) and reliability! It can rotate at least 180 degrees- 90 in each direction, with a classic 1.5-2.5 ms pulse. You can use any servo code, hardware or library to control these servos. 

For Arduino controls, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE. Position "0" (1.5 ms pulse) is middle, "90" (~2 ms pulse) is all the way to the right, "-90" (~1 ms pulse) is all the way to the left.

The default servo pulse widths (usually 1 ms to 2 ms) may not give you a full 180 degrees of motion. In that case, check if you can set your servo controller to custom pulse lengths and try 0.75 ms to 2.25 ms. You can try shorter or longer pulses but be aware that if you go too far you could break your servo!

NOTE: Operating servos close to or at stall torque reduces their life and will permanently damage them beyond repair.
