Make Sound with Arduino using Buzzer Circuit
This project shows how to Make Sound with Arduino using Buzzer Circuit. Buzzer makes sound when we send signal from Arduino pin. We can use it for alarms, alerts or simple tones. Two versions are used here one with components and one with buzzer module. Arduino Coding: Code Explanation: Parts List: Component Name Quantity Resistor […]
Sound And Light Metronome Circuit using Transistors
Music needs rhythm. A metronome helps us keep that rhythm perfect. This small project for Sound And Light Metronome Circuit using Transistors turns light into beat. When light changes then sound speed also change. It is simple, fun and easy to build. What is Metronome: Metronome is small device that gives steady beat. It makes […]
Audio Spectrum Analyzer Circuit using IC MSGEQ7
Music is not only for ears, it can be seen also. With MSGEQ7 chip we can make music dance in lights MSGEQ7 is a chip made for audio spectrum analysis. It divides audio into 7 frequency bands. Each band gives an output voltage. This voltage can be read by microcontroller. Like Arduino, ESP32, STM32 etc. […]
Arduino Text to Speech Voice Generator Circuit
This project make Arduino speak text. 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. Arduino Text to Speech Voice Generator Circuit is small and low cost project. Circuit Coding: Coding Explanation: Circuit […]
Arduino with Speech Recognition Circuit
This project shows how to control LED with voice using Arduino. We can use speech recognition module with Arduino Nano. It takes voice command. It turns LED ON or OFF based on command. This Arduino with Speech Recognition Circuit is simple project for beginners. Circuit Coding: Coding Explanation: Circuit Working: Parts List: Component Quantity Resistor […]
