Digital design

 its led based project which i implemented in my room. To make more efficient lighting. and its also helps to avoid light pollution in it.

at night with small intensity of light     

 with little less intensity

 

Its operated on 12 volts and controlled using micro controller individual led. there is 9x6 matrix so total 54 led light are controlled at time. controlling circuit.

as an application it can control or set at any intensity u need depend on the atmosphere and its also take some light sensors feed back.

          connection to led with matrix so by 15 wires. 9 for horizontal and 6 for vertical

 
now that LEDs are working based on the speaker out put and that speaker are connected with laptop.
so led are controlled by sound bit via controller.
