USB controlled RGB LED VU Meter PWM circuit 3 TLC5940 and one in 16 5mm RGB LED PIC18F2550 is being used. PC (Visual Studio C #) and microcontroller (Microchip pic c) have the source code of the software. USB Control software compatible with Windows 7 and Vista (XP does not support) also prepared by ExpressPCB circuit diagrams, printed circuit board’s files.
