Hi jus a quick question from an idiot - I'm really new to the whole electronics thing!
I've managed to make a circuit with LED's that works with a 9v battery. However I want to use a 9v DC power supply (that I use to power my guitar pedals - so negative tip) to power the circuit. I have a 9v 2.1mm socket (same size as the power supply jack), but don't know how to wire it into the circuit.
Am I right in assuming that as it's - tip, + sleeve, I wire the the sleeve of socket to the + side of my circuit and vica versa?
Only prob is the socket has a 3rd "prong" I'm not sure what to do with!
PLease help, I'm so close to finished my project! lol
