Dylanwad Posted June 15, 2010 Report Share Posted June 15, 2010 I had fun playing with some led's on a guitar I'd been messing around with recently. I've got 4 left so I thought I'd stick them under the bridge pickup on another of my guitars. It's a single pickup guitar with one knob and I don't want to add a switch so I was wondering if a push pull pot could be used to switch on the led's? This one maybe - http://www.axesrus.com/axeElectronicsPots.htm (8 down). How would I wire it up? Thanks for your help. Quote Link to comment Share on other sites More sharing options...
Ripthorn Posted June 16, 2010 Report Share Posted June 16, 2010 Any push pull pot will do, even an spst. You simply put the switch between either the +V lead from the battery and the LED or between the LED ground and battery ground. You can tie all of your LED leads together, but I would suggest using a current limiting resistor between +V and the LED anode. This will make your battery last longer and keep your LED's from burning up. I would use something at least in the 1k area for the resistor. So to recap, +V from the battery to the center lug of the switch on the pot, from one of the outside lugs of the pot through a resistor to LED anode, then wire LED cathode to batter ground. Easy as can be. Quote Link to comment Share on other sites More sharing options...
