ATtiny13 – disco lights using DFT
This is my another “disco lights” project which is an upgraded version of ATtiny13 – dance lights with DFT. This time I used a full implementation of optimized DFT 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 … Read more
