Introduction: How to Make LEDs Flash to Music With an Arduino This is a guide to make an LED flashing circuit that "beats" to an mp3 file on your computer, which can add an awesome effect to any sound-related device, or even your room (if you extend the concept with LED drivers or ...
The total cost of the electronic involves an Arduino microprocessor, a sound trigger, and a reed switch is around 20 dollars with the most expensive component being the Arduino microprocessor. In the lab we often use the 640 Einstein flash on the 1/256 power setting which the students m...
HC-SR04 ultrasonic echo connects to pin D3 on Arduino Nano. This device receives the bouncing pulse to get the distance between the food dispenser and the obstacle. It measures how long it took the pulse to travel and, using the speed of sound, we calculated the distance. SG90 servo conne...

This project guides you through designing, 3D printing, assembling, and finishing a custom Bluetooth speaker with a wood-like finish and great sound quality.
make loud noises such as shout, clap into the microphone, etc., we will get a loud reading. We will program the software for the arduino to light up the LED attached to digital pin, D13, when a certain threshold of sound is reached. The LED will light up for a half of second and...
In this project we will learn how to make an Arduino Alarm System. The alarm activates in 10 seconds after pressing the A button.
How to Make Arduino Lightsaber?My secondary goal was more esoteric. A Lightsaber isn't just an extended torch. There is also "The Hum"—that growling purr that lets you know you're holding something of immense power.In the movies, this sound effect is created by the legendary Ben Burtt ...
Pro Tip: Make sure you use data USB cable.There are two types of USB cables: charging-only cables and data cables. You need to use a data cable to communicate with Betaflight Configurator. Setup Once you’ve successfully connected to Betaflight, you will be greeted by the Setup tab with ...
An Arduino and an ultrasonic sensor along with the servo motor can be integrated to make a smart trashcan. If the bin detects some trash in front of it, it will open its lid automatically and the lid will be closed after a delay of some seconds. ...
