Guitar Pickup

What might the circuit look like for using a guitar pickup as an analog sensor with an Arduino (for detecting a moving string, of course)?

Thanks much!

hi

it will have to be a metal string, of course... there are instructions here for making your own pickups. Once you have that, you can use a bridge rectifier made out of 1N914's and a little capacitor and resistor to read the pickup's voltage. This diagram is almost exactly what you need.. just replace the transformer with your pickup, and put a 1K resistor across the capacitors.

Excellent - thanks. Will any diodes or bridge rectifier do? I'm not sure that I have those particular diodes around, but I'm pretty sure I can salvage something.

yes any old diodes will do it!

1N914=1N4148= most common switching diode...
