forgive my ignorance, and thanks for replies too,
but i was thinking that arduino has TX and RX (transmit and recieve) pins?
i thought this is what it was suppose to be used for..
honestly, i have no choice to use standard led strings... no magical ones haha
i am building a second wall pc and this time its a media server one with 7 HDDs and I want to have a thermal probe and Led to represent thermals between red and blue...
i have already ddone this with my first wall pc, that uses arduino mega and using only 12 pins of pwm.. (6 sets of red/blue) strings of Leds
so this new pc needs
thats 11 sets meaning id need 22 PWM pins...
heres the thing,
I am running a cute LED DEMO at startup to indicate all leds work by cycling through red/blue for each string like a chaser and actually looks cool haha
i would need to communicate to all strings on 1 program to acomplish this,
otherwise It's possible to edit the code for the 2nd arduino to delay to try and time the lighting correctly!!
i think i just answered my question.. adding a delay might work so long as boot time is the same everytime hahaha...
truly if I can run off 1 program it be much better :)
let me know guys...
