The sound sensor detects clapping or any loud sound, and sends a digital signal (HIGH) to the Arduino.Based on this signal: The Arduino turns ON the motor and LED.; After a few seconds, the Arduino ...

The Arduino Uno-compatible board has an MCS-51 (often called 8051 instead) instead of the usual ATmega328P/ATmega168. Specifically, [ElectroBoy] uses the AT89S52 .

Before going into the project, keep in mind that you can use an Arduino Uno or Nano board in lieu of the Seeeduino Nano board, but you should stay with the Grove Sound Sensor module. Even though ...

To celebrate its long-term success, we’ve collected 12 of the coolest, most revolutionary, and most entertaining Arduino projects currently in existence. Prepare to be wowed — and then inspired!

To build this project, all you need is three main components: an Arduino Uno, a 16x2 LCD, and a push button. You can connect everything to a breadboard to keep it simple.

It features over 5,400 projects, ranging from simple tutorials — like using a soil moisture sensor with Arduino — to more complete guides like building a Bluetooth-controlled car.

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.
