Digital Servo motor Sub-micro SG51R

Our Digital Servo motor Sub-micro SG51R is smaller than the 9 gram micro servos, it can rotate approximately 180 degrees (90 in each direction) and works just like the standard kind you’re used to but much smaller.  You can use any servo code, hardware or library to control these. Good for beginners who want to make stuff move without building a motor controller with feedback & gear box, especially since it will fit in small places. Of course, its not nearly as strong as a standard servos. Works great with the Motor Shield for Arduino or by just wiring up with the Servo library. Comes with a few horns and hardware.

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 (see here for an example sketch). 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.
