Summary of Multifunction RGB LED controller using PIC12F675
This project describes a multifunction RGB LED controller using a low-cost PIC12F675 microcontroller. It features five modes controlled by a single potentiometer and a button, with EEPROM memory to save the last used mode. The modes include automatic hue saturation color patterns, manual color selection, temperature indication via color changes, adjustable white light brightness, and an off mode.
Parts used in the Multifunction RGB LED Controller:
- PIC12F675 microcontroller
- 8-pin base socket
- BD139 transistor (3 units)
- 1 µF capacitor
- 330 Ω resistor (3 units)
- 470 Ω resistor (1 unit)
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 used for the vary the color variation 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 highest temperature
6, mode4 White light potentiometer used for vary light brightness
7, mode5 OFF potentiometer operation is disabled
