Step 6: Building the circuit That's why I made a instructable
friendly circuit image :) See photo 1. 1. Make sure you have all
the materials to make the circuit. And enough electrical wires
to connect all the components. 2. Before we build the circuit,
we first need to put the audio cable through the whole in the
back. 3. Build your circuit, and test it out. The best way to
test it is through your audio output from your computer. Make
sure the audio on your computer is set to 100% and then test it.
Circuit: The positive pole from the adapter goes to the positive
leg of the first LED. Next the other 5 LED's follow. Hook the
negative leg from the first LED to the positive leg of the
second LED. Hook the negative leg from the second LED to the
positive leg of the third LED, and so on. The negative LED from
the last LED goes to the center pin of the TIP31. Then hook the
right pin of the TIP31 to the negative pole of the adapter. All
there's left now is to hook up the audio cable. Hook the red or
the white wire fr
