ATtiny13 – disco lights using FFT

This is my another “disco lights” project which is an upgraded version of ATtiny13 – dance lights with FFT. This time I used a full implementation of FFT algorithm with reduced memory access to compute a power spectrum of audio signal. This version has also 3-channel lights but visual effects are much-much better! Required Parts ATtiny13  – i.e. MBAVR-1 (Minimalist Development Board) … Read more
