Clap-Activated LED

This project lets you control an LED on and off using claps or similar loud sounds.

Components Required

• Arduino (Uno, Nano, etc.)
• Sound sensor module
• LED
• 220-ohm resistor
• Jumper wires
• Breadboard (optional)

Connections

• Sound Sensor

  • AO (Analog Out) -> Arduino Analog Pin A0
  • • (or VCC) -> Arduino 5V
  • G (or GND) -> Arduino GND

• LED

  • Positive Leg (+) -> Arduino Digital Pin 2 (through a 220-ohm resistor)
  • Negative Leg (-) -> Arduino GND
