9Audio LED Visualizer
In this project we’ll use a sound sensor that will light a series of LEDs depending on the beat and volume of the sound it detects.
PARTS REQUIRED
Arduino board
Breadboard
Solid-core wires with ends stripped
Jumper wires
2 red LEDs
2 yellow LEDs
5 green LEDs
9 220-ohm resistors
3.5 mm female headphone jack
HOW IT WORKS
In Project 2 we created an LED night-light that was controlled by a light sensor. This project is similar, but the LEDs will be controlled by sound. We’ll connect a headphone jack to the Arduino, hook the jack ...
