Robotic Servo Arm

Servo arm without a hand. I better make one.

The code is just Knob (in the Arduino IDE), only that there is three servos and three pots.


I made all this on a Compact Disc Drive case cover (metal) and hot glued the servos on top. 




Three servos. Two normal size, and one RC Helicopter mini servo.

LED for temporary use

These two 4700μf capacitors are for smoothing. You need them. If you don't have them, the servos will stop the Arduino because of the current the servo draws.
I also recommend the diode (IN4007).
