hey guys i always wanted to do some simple rgb led thumbsticks but after looking at kits online they seem a bit overkill as far as design goes and at 15$ per kit no thanks!!!!!
so i shared this idea with sethmods and he got started on the code right away dam wish i never dropped coding a long time ago lol
so we came up with this its sethmods code 100% and i designed the pcb
uses a 12f683 and pnp transistors sot 23
decided to make it as small as possible for my own preference and i think it came out good has enough for 4 diffused rgb leds 3mm
let me know what you guys think yet to test as i cant find a resistor i need im sure i have it but i gotta dig through my stuff
and i need to buy some rgb leds
might be able to finish tomorrow as no stores are open today example radio shack to go buy parts

Nice!. Post Up When You Finish.

I have written something similar for my mod off entry, what exactly are you doing with this like a continuous RGB fade?
You designed the circuit for common anode right, so current gain with pnp emitter followers, I really want to design mine to be able to soft-switch between C-anode and C-Cathode RGBs. Not sure what I am going to do to account for sourcing and sinking, bah my analog electronics is not fantastic, tis why I have friends.
Scratch that I think I worked it out.
-
no fade just color cycles red green blue yellow purple etc
and yes common anode

I like this, I have a wired pad that has 2 clear thumbs ready for leds (compliments of timmay) after seeing a video of these bad boys in action I may pick a set up off you

If you are just using the 12F683 for RGB LEDs, you can easily get breathing and fading effects. The code is simple enough. Just activate one timer and use a simple interupt to change some values.
Theres an example in my Spectrum code:

With some effort, you could even make it self programmable with 2 inputs.

You get one wired up yet? I'm still waiting on mine to come in the mail. i got my rgb leds already and which resistor do i use?
-
Question to 3D0: Out of curiosity what are you doing to drop voltage from the red LEDs here?

package shouldve been there already?
not surprised if you havent got anything yet usps lost 3 of my packages 2 to my nephew and another i was getting from ebay
use a 15k 0805 resistor send me email if yo do not receive today so i can reship no biggie
and @ghost not sure sethmods did the code i just made the pcb
-
It was something that I coded up in an hour or so. There are 3 arrays (one for each color). Setting the value for each index sets the duty cycle for each color. The red just has a much lower duty cycle.
Sorry for the letdown. It was something I was trying to pump out quickly.
-
no let downs. the fading and such was just a suggestions.

was really looking forward to this as i got some rgb leds laying around doing nothing. Thinking of modding my psp 3000 and i know these will come in handy.
