Hi,
Totally new to all this.
I have 2 sketches that both work separately that I would like to combine.
int leds[7] = {6,7,8,9,10,11,12};
void setup(){
for (int jj; jj<sizeof(leds)/sizeof(int);jj++){
pinMode(leds[jj],OUTPUT);
delay(5);
}
}
void loop(){
digitalWrite(leds[random(0,sizeof(leds)/sizeof(int))],HIGH);
delay(random(20,200));
digitalWrite(leds[random(0,sizeof(leds)/sizeof(int))],LOW);
}
Also...

// Breathing effect
// Color shifts from hueA to hueB as it pulses.

// Set A and B to the same hue if you don't want the color to

I've tried several different thing, none of which have worked.
Any help would be much appreciated.
Indeed, and I've looked, but every method I've tried yields compile errors of one sort or another. Also I did say I'm new to all this. My only programming experience is HTML and a little Javascript. I'm Stuck.
Then post the code that gave you the errors and post the errors. Then we can help you.
Read the how get the most out of this forum sticky to see how to properly post code. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code in code tags.
Please include the entire error message. It is easy to do. There is a button (lower right of the IDE window) called "copy error message". Copy the error and paste into a post in code tags. Paraphrasing the error message leaves out important information.
One obvious problem is that both sketches have an object called leds. It might help to change that in the smaller one and fix the resulting compiler errors before trying to merge.
Okay...
I've manged to merge the sketches and they work fine(ish) together.

No error codes, yay!
However...
The "Breathe" effect on the WS2812B Strip is not running as smoothly as it was, it's a lot more jerky.
Is this likely to be anything I've done wrong in the code?
Lol
