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!
