Anyone can hang a poster from the wall, but if you're willing to put a little DIY into your home decorations, this Arduino-powered LED wall-art looks amazing, and reacts to music playing in the ...

What is the purpose of an Ultrasonic sensor? --An ultrasonic sensor is an electronic device that measures the distance of a target object by emitting ultrasonic sound waves, and converts the reflected ...

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 ...

Electronic systems can help the visually impaired. This project combines an Arduino Nano, a TCS34725 color sensor and a buzzer to assist color blind users.

The sound sensor module will capture the sound using the onboard microphone and will give an amplified signal at the output. The frequency of this signal will then be calculated using an Arduino ...

The SparkFun Arduino Pro Mini 328 5V/16MHz serves as the brain of the operation, controlling the RGB LED strip and the wireless charging module.

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

The hooter connects to the normally-open (NO) contacts of the relay. When the flame sensor detects a flame, it triggers two actions: the three LEDs light up for visual indication, and the hooter ...

In this article, I have added three sensors with Arduino UNO and user can choose the required sensor with the help of keypad.
