- 1 x TIP31 NPN Transistor - Radioshack # 276-2017
- 1 x 1/8" Audio Jack - Radioshack # 274-0249
- 1 x Toggle Switch (i used a covered one because i thought it looked cool, but any will work) - Radioshack # 275-601
- Roll of LED lights (or whatever you plan to use for lights) These are the cheapest i found and they included a power supply
Here is video of them in action
Step 1: Build the circuit
Cut a piece of breadboard to the size you want to build your circuit on.
You will also need to desolder the 12v end from the LED strip to be able to wire it into your circuit.
Wire two leads onto where you remove the 12v end from
Step 2: Wire Switch and Audio In
The audio is only wired in from one channel, i used the left channel but you could use the right. I eventually want to have two circuits set up and have different colored lights for each channel.
