Arduino light organ

A Psychedelic light organ of 80s

Psychedelic light organ of 80s style, developed with an Arduino and a FFT library for the analysis of the signal obtained by an analog input.

The project uses a microphone to get the signal, which is then adapted to the analog input of the Arduino.
Also included is a power amplifier based on triacs and optocouplers.

Arduino Christmas light controller

A practical Christmas lights controller, with 8 channels utilizing solid state relays. 

A simple Arduino project to control de Christmas light. WIth 8 channels utilizing solid state realys. They are solid state relays, good for about 100watts AC, draw about 17ma, so I can run them directly off the CPU pins of the Arduino with no extra circuitry.
