Summary of Multifunction RGB LED controller using PIC12F675
This article describes a low-cost, multifunction RGB LED controller built around the PIC12F675 microcontroller. It features five operational modes controlled by a single potentiometer and button, including automatic color cycling, manual hue selection, temperature indication, white light dimming, and an OFF state. The system also includes EEPROM memory to retain the last selected mode upon power-up.Parts used in the Multifunction RGB LED Controller:
- PIC12F675 microcontroller
- 8 pin base
- BD139-3 transistor
- 1uF capacitor
- 330 Ohm resistor (x3)
- 470 Ohm 1A resistor
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
