I am assuming that you have a little bit of electronics and soldering experience. I will also assume that you have some familiarity with Arduino.You will need
- A voice changer module. (8$ at Wallymart)
- A 741 opamp ic.
- an LED of choice (not necessary, but provides a cute little visual input that things are working, and will provide clues as to how to change the circuit into a LED light organ.)
- a resistor for your led (220 ohms - 1 k will work alright, you only need this if you are using the LED)
- some hookup wire.
- Soldering iron and solder
- wire snips
