Introduction: 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

Hi Justin, I am starting a computer engineering course at my school and would like to try building this. I have everything already except the LED strip, but that is easy to come by. Can you also if possible send me the programming (PICBasic or even in a text file) so that I can get my students to perhaps just program one sequence? This is VERY COOL!!! email:jbiro@cogeco.ca

Hey! I was asked to do a simple pic project for school and this is great, but I have to understand and explain how the code works and I see you only posted the .hex file, could I get the original code please to razielconz.7@gmail.com? You'd help me out a lot!

Also, do you think something similar could be done to drive an RGBA luxeon-like LED?

can this code be put on a pic 16f627-04/p chip? it has 8 legs but im sure I could put it in the circuit if the code would work.

author
Jestin_Cubetech (author)aclark322013-10-09

hmm no...
The 12F629 is almost exactly identical to the 12F675
- the only difference is that it does not have an ADC.

aclark32 (author)Jestin_Cubetech2013-10-09

thanks for the reply and the code... looks like Im just gonna have to go buy me a 12f675 then. Im lucky enough to have an ESCO store in my city and they stock just about any pic controller you could want.. they stock a lot of other stuff too... the only part Ive ever had to order there was a mosfet for a Rockford fosgate amp I was repairing... look for one in your area.. its called ESCO,,, Electronic Supply Company...
