Hi, thanks for you input.
I have done as you advised in your post but for some reason I can't get the breadboard to hold the voltage, it seems that running 3 servos off a modified 9v power supply to produce 18v isn't enough.
As advised I need to run 5 servos off this and when running a volt meter on the breadboard it was only producing 1.8v can you advise why this may be the problem.
cheers
