This simple circuit makes a normal buzzer produce a chirping or tweeting sound; it uses a 9 V battery, two push buttons, one capacitor, and a buzzer, also the circuit also does not need a microcontroller or IC. Also, it works on charging and discharging of capacitor and this Chirping Sound Buzzer Circuit is good […]

Make Sound with Arduino using Buzzer Circuit
This project shows how to Make Sound with Arduino using Buzzer Circuit; also buzzer makes sound when we send signal from Arduino pin. Here, we can use it for alarms, alerts, or simple tones; moreover, we use two versions here: one with individual components and another with a buzzer module. Arduino Code: Code Explanation: Parts […]
Sound And Light Metronome Circuit using Transistors
Music needs rhythm and a metronome helps us keep that rhythm perfect; also this small project for Sound And Light Metronome Circuit using Transistors turns light into beat. When light changes then sound speed also change and hence, this project is simple, fun and easy to build. What is Metronome: Metronome is small device that […]
Audio Spectrum Analyzer Circuit using IC MSGEQ7
Music is not only meant to be heard; it can also be seen and with the MSGEQ7 chip, we can make music dance through lights. IC MSGEQ7 is an integrated circuit designed for audio spectrum analysis and it divides an audio signal into seven frequency bands and produces an output voltage proportional to the signal […]
Arduino Text to Speech Voice Generator Circuit
This project make Arduino speak text, as it convert text into speech; in this article we used Arduino UNO board, LM386 audio amplifier, speaker and some components. Arduino send digital voice data and IC LM386 make sound loud and also Arduino Text to Speech Voice Generator Circuit is small and low cost project. Arduino Code: […]
Arduino with Speech Recognition Circuit
This project shows how to control LED with voice using Arduino and we can use speech recognition module with Arduino Nano; also it takes voice command. It turns LED ON or OFF based on command and also this Arduino with Speech Recognition Circuit is simple project for beginners. Arduino Code: Coding Explanation: Circuit Working: Parts […]
