this video is about how to make a led midi controller using Arduino and fl-studio to synchronize between music and lights in order to make a led show .Also the same principal can be used to control other things than leds like fountains ...

An Arduino project that uses a led stripe and a microphone to synchronize the leds to the recorded music in realtime

The project shows how to synchronize music to a LED, designing and building a low-power audio amplifier/speaker driver based on a LM386N, a LM358 low-power dual Op-Amp, and a 2N3904 NPN Bipolar Junction Transistor. The LM386 is a low power amplifier. Its default voltage gain is 20, which can be vary by placing an RC circuit between pins 8 and 1. Its gain can be vary to any value between 20 and 200. LM386 is biased by an external DC power source so it provides power to the AC signal and hence enhance the AC signal. That why its output signal is greater than its input signal. The voltage rating of power supply must be between 4 – 12 volts and current rating greater than 100mA for its proper working. We can control the gain and also remove the noise from the signal. It can be used in ultrasonic drivers, portable audio players, in TV sound systems, servo drivers, line drivers, in radio amplifiers, especially in AM and FM, and power converter. Building a summing amplifier around the LM358, we are combining several inputs into a common output signal and bringing clearness to the sound. Audio speakers convert electrical signals into mechanical motion. The electric signal is passed through a coil of wire (the “voice” coil), which is suspended a strong magnetic field provided by a permanent magnet. A time-varying current in the coil leads to a mechanical deflection relative to the magnet. Placing the 2N3904 we are amplifying the power as well, since is a general-purpose transistor, and act as another filter to bring clearness to the sound. At the output a LED is placed with a 6ohms resistance, in order to synchronize the tone frequency with light. For sound input an Arduino Uno is used generating a melody at different frequencies to create the flash in the output LED. For programming this Arduino, a MATLAB application is used with the code attached.

The Audio Amplitude-Based LED Controller offers a novel approach to augmenting audio experiences by synchronizing LED lights with the amplitude of audio signals. This controller provides users with a dynamic and immersive lighting effect, enhancing their engagement with music or audio playback.

An Arduino-based music-reactive lightshow that uses RGB LEDs to create dynamic patterns synchronized with the rhythm of music. The system captures audio signals through a sensor/microphone module and drives RGB LEDs to blink, fade, or change colors in real-time according to sound intensity and beats.

A lightweight python script to synchronize your Govee LED Strip (Bluetooth) with your Spotify music. It continuously monitors your current playing track on Spotify, extracts the dominant vibrant color from the album art, and smoothly transitions your LED strip to match.

Flicker Lights is a project made up of software for playing back a music synchronized light show, creating a light show, and also a base station for streaming the show to NRF24 nodes with LED strips

BeatSync Hats is a self-contained wearable system that reacts to live music by syncing LED patterns to the beat. Each hat independently senses ambient audio and extracts rhythm in real time, creating a crowd-level synchronized visual effect without wireless communication, phones, or external controllers.

A hacky implementation of synchronizing limitless WiFi LED bulbs to music

A project aimed to synchronize my led strip to music based on frequency. For Windows.

A passion project of mine : an Android App that allows the user to send IR signals to a LED strip controller that are synchronized to the output of the phone (music mostly)

Designed a music-reactive LED strip system using Arduino Nano and a sound sensor to synchronize lighting with audio signals. The system processes real-time sound input to control LED patterns basn embedded systems, basic signal processing, and hardware interfacing. Technologies: Arduino Nano, Embedded C/C++, Sound Sensor, LED Strip, PWM Control

STM32 Interactive Music & LED System is an embedded project that plays multiple melodies using a speaker while creating synchronized LED lighting effects. The system allows users to switch between different songs (Anthem, Happy Birthday, Twinkle Twinkle, Police Siren, and Pirate theme) using a push button.

The idea is to create a Master Writer/Slave Receiver configuration which will allow each individually programmable LED strip to synchronize to the beat of music playing via a speaker while reducing any noise in the environment. The Master Writer/Slave Receiver configuration via the i2c protocol will be connected to the bluetooth speaker, two unit controlled strip LEDs which concurrently light up with the beat/bass of the music being outputted through the speaker recorded by Piezo vibration sensor, and the synchronization mode will be controlled in a separate unit via the user through a button system.

A distributed LED choreography system designed for group performances. Each device (e.g., Arduino with FastLED) is assigned a role and listens to beat signals via MQTT. A central controller sends synchronized beat indices during music playback, allowing each device to independently trigger color and lighting effects based on its role.
