I am starting this project to learn more about firmware and servos.
This idea was from Glenn(Click Here). Actually he asked me to create a
Vorpal Robot. Looking at the number of servos, I was thinking of creating a whole hand instead. It would be kinky to have an extra hand.
Where to get the hardware?

No Servo, How to Test
If you have no servo, you can use PWM pins connect to a 1000 ohm resistor then to led, if u are using a 2v led. Hope this helps.
