I hacked a rotary phone into a radio! Pick up the phone, choose a country and a decade, and listen to some great music!
An Arduino based MP3 player with 30 levels of volume adjustment, 5 levels of EQ adjustment, and a pretty cool retro looking UI.
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.
FFT spectrum analyzer is a test equipment that uses Fourier analysis and digital signal processing techniques to provide spectrum analysis.
