Most stereo systems have some kind of music level indicator, The indicator may be as sim pie as a set of LEDs, ordinary low-voltage lamps or V-U (volume-unit) meters. These were later replaced by bar-graph type LED indicators. Though attractive, they provide only one-dimensional ‘movement’ of LEDs with the music. Now this system has also become very common.

Presented here is a spectacular system to replace the outdated music level indicators. This system is capable of providing a smart, two-dimensional ‘dancing’ effect on a square matrix of 100 LEDs.

In this system, out of 100 LEDs arranged in a square
