Arduino Audio Meter Specifications: – Based on Arduino UNO board for signal processing (16MHz, 1KB RAM). – Analog input/output stages using MCP6002 rail to rail op-amp. – The original audio ...

This is my first project for IT 254, it receives audio input from a microphone and classifies that audio as either loud or quiet. Then sends that information to the Arduino to indicate with an LED. - ...

This project combines song recognition with an interactive light display to create an engaging user experience. By integrating various hardware and software components, we built a system capable of ...

It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than others. For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino ...

User input is provided by a digital encoder with push-button. A set of four MAX7219 chips control the entire 256-pixel matrix with just three pins on the Arduino.

The audio amplifier has a volume control, and the inputs and outputs can be selected via button presses. An Arduino Pro Mini takes care of switching the relays based on the button presses.

Rock your next party with an expandable DIY audio player with equalizer! This is the first part of a two-part series exploring the design and implementation of an FPGA-based audio player with ...

Meet the Production-Ready Arduino Compatible HQ record and Playback Audio Module! With ease, you can record and playback up to eight sound bytes using your own voice, or PC. There is an on-board ...

Have you ever wanted to know what is inside a digital audio mixing console? Or have you already programmed some MP3-player based on an ESP32 and the great Arduino libraries, but without the option for ...
