Multifunction RGB LED Controller Using PIC12F675

multifunction RGB LED controller using low cost PIC12F675 microcontroller.

features:
1, 4+1 mode operation a single potentiometer and single button switch used for multiple operation
2, EEPROM Memory option for mode selection :- the last mode will be saved.

3, mode1 automatic hue saturation RGB LED light color pattern - potentiometer is using for vary the color changing speed.
4, mode2 Manually select a color from hue saturation color chart using pot.
5, mode3 Temperature Indicator blue color represent low temperature and red color for high temperature
6, mode4 White light potentiometer used for vary light brightness
7, mode5 OFF potentiometer operation is disabled
