After I graduated I decided to implement a music visualizer at home using a led strip, Arduino board, and a sound detector. I used Arduino Nano and a Sparkfun sound detector. The sound sensor takes ...

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 ...

Users will need to provide their own Arduino Pro Mini and the hardware features a 1.4 W, 8 Ohms, Texas Instruments TPA2005D1, 14 bit ganged PWM, PWM 8 kHz low pass smoothing filter all powered by ...

They’re using a cheap sound sensor module and an Arduino to catch instantaneous photographs, with students caught in the act of popping balloons. The goal here was to keep things as simple as ...

He builds a simple dead bug Arduino (which he calls an Audioino) using a handful of resistors, a pair of caps, an LED, a reset switch, and most importantly – an audio jack.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

In this project, we're making a cool 4×4×4 LED cube with Arduino Nano. LED cubes, also known as LED Matrix, can light up your room, study space, or Maker area giving it a awesome cool look. Moreover ...
