Standard Metal Servo (MG945)
This high-torque standard servo now comes in a metal-gear flavor, for extra-high torque (10 kg-cm!) and reliability! It can rotate at least 180 degrees (90 in each direction) with a classic 1.5-2.5ms pulse. You can use any servo code, hardware or library to control these servos.
To control with an Arduino, we suggest connecting the orange control wire to pin 9 or 10 and using the Servo library included with the Arduino IDE. Position "0" (1.5ms pulse) is middle, "90" (~2ms pulse) is all the way to the right, "-90" (~1ms pulse) is all the way to the left.
The default servo pulse widths (usually 1ms to 2ms) 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 0.75ms to 2.25ms. You can try shorter/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.
