This is just about the cutest, tiniest little micro servo we could find, even smaller than the 9 gram micro servos we love so much. 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 servos. 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 servo. 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.
