Hello,

Is it possible to control a few servos off the Arduino, or do they need their own power source. If the do need their own power how would I set up the circuit?


Thanks,
Drew Davis

Runaway Pancake

A similar inquiry was made recently.



You wouldn't need the 7805 if you're using an Arduino board, but he had his own 'boarduino' set up.

Fair enough?

Hey, it's "bipolar transistor" or "junction transistor" - "BJT" is just stupid.

Please forgive me, (I'm completely new to Arduino and electronics)  but I don't really understand the diagram.

1. What is a 7805

2. Where do the thin black wires coming off the servos go.

3. how does a 9v battery become 5v

4. what is a "boarding"

Thanks,
Drew R. Davis

Runaway Pancake

1) If you're using an Arduino board then disregard.  Just figure it's a 9V cell connected to the Arduino board
2) Servos have 3 wires; +V, Gnd, and Signal. Those are the Signal wires
3) See #1
4) Not "boarding" - "boarduino", it's an Arduino set up on a breadboard

The two links in my signature should also help, they basically show what runaway pancake is suggestion in action - and also what you can expect your Arduino to do if you do not to it the way we are suggesting.
