hi,
thnx for the replies,

Unfortunately i still cant run anything from the 5v pin, despite doing everything in this thread.

I've decided to get a cheap bench top variable lab power supply to power my servos, as well as a new arduino & the motor shield from ladyada's site, just in case my arduino's faulty

I've decided to get a variable power supply as all the voltage ratings seem to be different for different servo's.

I was wondering can i run the bench lab power supply directly into a breadboard, without needing a special circuit or something to run it through?

The bench top power supply is from here

thnx

You can wire up the breadboard as in this picture: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1250070061/6#6

Replace the battery power leads with those from the powersupply.

Don't forget to connect the grounds.
