Portable Party Toque with Built in Amplifier and Visualization LED

Step 3: Add the LED organ

Find a little free spot on your proto-board, and put in the LED organ. Don't forget to give yourself a bit of a lead for the LED as you
may want to place it specifically as I did.

I tried to place mine near the mouth of the Instructables Robot, so he'd look sort of like he is singing along with the music.

This circuit is super simple and adds some fun flair to the whole project. You could just use this circuit as a stand alone as a visualizer for any number of outputs. That is why I have included it as a separate step.

If you find that your sound has become distorted when you hook the LED organ up, you can try putting a small cap across the ground and input pins to smooth the signal.

Here it is in action.
