A simple audio visualizer that maps the audio signals from ADC to LED strip. The number of lit LEDs is based on the amplitude of the audio signal, with a brighter peak indicator on the highest ...

One of the coolest things any sound system can have is some kind of musical visualization. Thumping level meters that pump with the volume are a great example, and were particularly popular in the ...

Humans love visualising music, whether it’s in the form of an inscrutable equation drawing squiggles in Winamp, or a simple VU meter pulsing with the beat. This build from [mircemk] is of the latter ...

Finally 7 Vus and 11 patterns working on Arduino Nano and Arduino Pro Mini 3.3 volts. I say finally working because on the Arduino Nano when using Adafruit's Electret Microphone Amplifier - MAX4466 ...

Anyone who follows my articles here at TweakTown knows that I am a sucker for new Arduino-compatible development kits, and I especially like the micro-sized boards that are easily hidden inside ...

Discover how you can build a professional digital multimeter using Arduino that measures up to 24V DC voltage, checks resistance, conducts diode testing, and performs continuity tests. This ...
