This project uses a sound sensor to detect a "clap" (loud noise) and toggle an LED or appliance. Hardware Needed: Arduino Uno or similar board. Sound Sensor Module (e.g., KY-038 or similar). LED (with a 220-ohm resistor). Breadboard and jumper wires. The Code: : Projects using TFT color screens to show sensor data
: A memory challenge using buttons and LEDs. infrared motion detectors
If you're looking for a different "piece" or component, the book also includes detailed instructions for:
: Projects using reed switches, infrared motion detectors, or ultrasonic distance sensors.
: A door entry alarm that logs timestamps to an SD card.
