Hello,
I'm very new to designing and building electronics involving anything outside of simple Transistors, resistors, capacitors, and diodes. I have a fair amount of experience with the parts previously listed and they may be the only parts I need for the task I am currently requested aid in building because I am incompetent when it comes to apply the simple knowledge I know in electronics. I am attempting to build a circuit which will drive about 80 5mm RGB LED lights in syncronized slow on/off oscillation. To specifiy the term slow on/off oscillation, I am hoping to use a circuit which will provide DC power to these lights which gradually increases magnitude and then decreases in magnitude so that the intensity of the lights will oscillate as they change color. These RGB LED's possesses a common anode so I was also hoping to implement some IC which randomly distributes the electricity to each color cathode so that a syncronized yet new color is generated by the 80 LED's with every slow oscillation of color.
Esentially I am asking what circuit would generate a Sine wave or sawtooth DC signal, and is there an IC which can randomly distribute this signal across different anodes? I know that this can probably be accomplished with a PIC or a microcontroller but i have no experience with either of these parts.
Thanks,
Duck
P.S. I have googled this but I am overwhelmed with reasources describing AC power
