This is a project of a lamp made for the New Year's Eve. Matrix consists of LEDs 3x15 in RGB colours. Processor AT89C4051 was used as a counter. The colour change takes place in the rhythm of the music via built-in microphone from which the signal is passed through a low-pass filter or using a generator with adjustable timing. Additionally, a strobe function was built in (all LEDs light up simultaneously) with an adjustable speed.
The whole device was closed in a housing from a halogen lamp.
