Intro: Dancing LED's

Create LED's to dance to your music!

You will need:
• a small 8 ohm speaker
• code 104 capacitor
• 35v 10 uf capacitor
• LED (single- or multi-color)
• Audio transformer
• breadbord
• Audio cable

Step 1: Start the Build

Put the audio cable L/R in the rail's positive and the negative in the negative rail.

Step 2: Capacitor

Put the capacitor in the other rail so stop tearing in the speaker.

Step 3: LED

Add an LED in the same rail as the capacitor.

Step 4: Add the Transformer

Add the smaller coil on the led's rail.

Step 5: Finish the Transformer

Add the larger coil to the audio input rail.

Step 6: Add a Capacitor

Add the 10uf capacitor from the audio rail to the breadboard and connect a speaker to the same pin. Connect the negative of the speaker to the negative of the audio rail. Plug it in and play!

    The transformer is used to amplify the audio signal enough to light up the LED. you can buy them at your local radioshack or similar. Hope that helped :D
