Hi I’m just starting project to add “eyes” to trio of small "found objects” robots

RGB Neopixel Jewels fit the eyes perfectly (they are old opera glasses) although a tight fit, leaving room for diffusers. As a result the orientation is not quite consistent between the eyes. You can see in the diagram the order of the LEDs.

I want to apply effects that treat the “pupils” of the eyes (LEDS 0,7,14,21,28 and 35) differently from the surrounding LEDS. That’s would be easy enough.

However, I also I want to be able to apply effects that sweep horizontally i.e. starting at 6, followed by 1+5, then 0, 2+4, 3, 8, 9+13………

Likewise for vertical sweeps (top row, middle row, bottom row i.e. 1+2+9+10+15+16+23+24+29+30+37+38, followed by 6+0+3………) etc. You get the idea.

I’m happy to roll my sleeves up and just hack it all out, but I have to wonder whether there are any “tricks” that might help!?

I’ve taken a look at array sets but I’m not finding out enough to help me really use that approach, so any pointers appreciated. Any other thoughts would be very welcome too.

Thanks

@Ken_Douglas - - Look at my code in:

It illustrates how to use arrays and arrays of arrays to create custom animations like you want to do. The_8x8_Arrays.h file shows the arrays and array of arrays that I used. Here is a video of that code in action:

@Ken_Douglas i would create a class ‘eye’
And a class ‘google’ which would be a left ´eye’ and a right eye’´
You could have
E1=eye(0,1,2,3,4,5,6) which will correspond to eye(pupil,up1,up2,right,down2,down1,left)
Then you create all the method for what you wanna do with the eyes without having to think about which led numbers you use
I hope I am clear

Thank you Yves and Ken, for your very useful help. I’ll let you know how I get on.
