Turn your New iPod Nano into dancing Robot

For this project, the developers have developed very simple way to control two servo motors by iPod nano: using the sound from headphone jack as PWM signal that controls the servo motors! Yes, two servos are powered by miniature 3.7V 110mAh Li-Po battery and control lines are directly connected to headphone jack! Very simple!

They also used this technique in the iPad and iPhone robots, what? From the headphone jack "sound" is a method of using ultra mon snap as a signal directly to the servo motor control? Servo 3.7V 110mAh Lithium Polymer they moved in, and headphone lines are directly connected to the I! Named the "DSSD" (Direct Sound servo drives)
