iPods are making a comeback, but they’re getting harder to find, so I decided to build my own.
With a low-cost ESP32 and WM8960, we built a complete real-time stereo parametric EQ with professional-style controls and presets.
A Pi 4 and a cheap USB mic tell dialogue from explosions with an on-device voice model, then click your TV's volume over Wi-Fi or IR.
Walk through a recorder export with a local Python inventory and a reproducible byte-layout example.
A stereo VU meter built with an Arduino Nano and two NeoPixel LED rings.
Experience the tactile nature of a vinyl music collection (but without actually owning any vinyl) through Sonos, Spotify and NFC tags
An electronic keyboard with 7 piano keys, programmed to Middle B/A/G/F/E/D/C, and an 8th button used to access a menu of preset songs.
Use C.H.I.P. to make any old speakers AirPlay speakers. Use several C.H.I.P.s to make a network for a multiroom audio experience!
A Mac script splits any song into 4 frequency bands so the NU40 DK's 4 onboard LEDs flash to the beat. No extra parts needed.
This experiment clearly shows how much the enclosure can influence the sound of even a tiny and inexpensive full-range driver.
It detects a beat in a line level audio signal.
This project is similar to my previous one but uses the FHT library which turns out to be at least 4 times faster than the FFT.
Arduino taking! Home automation.
As a musician and music passionate, this little Keyboard is my first (but not last) Arduino project. Hope you have fun with it :)
An update of the older version of the keyboard. Now it doesn't require switches on your breadboard, you can use your pc keyboard.
Make beautiful music with Adafruit, SparkFun, Arduino and ProtoStax! Create an RGB matrix audio visualizer with Arduino.
How to play audio file by using DF Player Mini.
Visualize sound frequencies spectrum with an OLED 128x32 display, Arduino Nano 33 BLE and an electret microphone amplifier (MAX9814).
Just a basic sound sensor activated LEDs with an optional LCD for sound level data. ***STROBE LIGHT EFFECT AT AROUND 8:45 MINUTE MARK!***
A simple DIY project which can be done by anyone!!!! Make Arduino Nano sing your favorite songs with a buzzer!!!!
Thanks to the "Charlieplexing technique", the construction is drastically simplified
Simple to build and useful instrument for your lab.
RGB LED backlight with audio signal visualization for room/desk backlightning...
A simple single transistor amplifier dramatically improves audio output of projects.
