Clap-activated LED Array

By the end of this instructable you will be able to build a device that listens to loud noises like claps and responds to them by turning on or off 3 LEDs. Above is an image of the final result.

You will need:

Arduino Uno
Breadboard (see step 3)
4 Male-Male Jumper Wires
3 Male-Female Jumper Wires
3 LEDs
3 220 ohm resistors
1 KY-038 microphone sound sensor module
You can purchase these parts online from various places - search around and you should be able to find these at a decent price.”
