I'm about to begin a project in which I need to control three servos,
and my idea of what my project would look like is in the picture below
(made in Fritzing). First of all, can this work? I have three 4.8-6 volt
servos connected to the five volt on the arduino. If not, how do I fix
this? In addition, I'm new to the forums, and probably uploaded the image
incorrectly, so it's attached as well. Any help with that would be great,
too! Thanks!
No, you cannot "power" 3 servos from the Arduino 5V pin, you can barely even be successful
powering 1 servo from the 5V pin. Get a separate power source for the servos, eg 4 Alkaline AA
cells in series, or 5 NiMH AA rechargeable cells.
You will still connect the ground wire and 3 signals between the Arduino and whiteboard.
Hi,
As oric_dan says, have a quick look at the two links in my signature below for why your original plan will not work and a simple suggestion for getting it to work.
You might need batter batteries than suggested in the link for 3 servos depending on thier size.

DuaneB, thank you very much for your response! This is exactly what I was looking for!
