First servo test successful!

This is one servo in my gripper, controlled by the most basic arduino sketch that cycles from one position to another. This is also a test of my external power supply as you can see the arduino is not powered via the USB port in this video. It is powered by a center pin positive 7v 2500mA DC power supply, which hopefully at 2.5 amps can easily power all 6 servos in my robotic arm.

The power for all the servo's doesn't go through the arduino, it comes from the power supply. This was merely a test of a single servo. Although you can see the servo here is connected to the duemilanove 5v and gnd pins, in the arm they will connect to the power supply direct.

The Arduino can't provide that kind of current no matter where you plug it in but you can use it to control another circuit (like a motor shield) that can drive your motors.

Did you make this gripper yourself, or did you buy it from somewhere?

Im doing a similar project myself.. also with the arduino
