A meter is optional but can really go a long way in helping you resolve issues. I highly recommend getting one for any of you circuit projects.
This instructable provides a walk through of a basic servo driver using a 555 IC chip 5 resistors a transistor and 2 capacitors. The idea is simple, use 2 switches to control the motion of the servo. Note this circuit is based on a servo tester circuit found on the Internet.
We built this with parts from Jameco Electronics at an instructables build night at Arch Reactor Hackerspace. Thanks Jameco!
Step 1: The circuit
This is a diagram of what we are building. This and many other 555 circuits can be found on www.555-timer-circuits.com
