Folks, I have a Neo-Pixel LED and want it to blink like a heart beat. Just wondering if anyone has any ideas on how to do it.

This is one idea I made up just now messing around. This was posted with flows but was problematic in rendering/showing the flow. [{"id":"4d9e128f61b30b9a","type":"trigger","z":"a1911aa3.c45be8","name":"","op1":"40","op2":"0","op1type":"num","op2type":"num","duration":"250","extend":false,"override…

I'm not seeing anything in your flow visual, although it appears to be formatted correctly...

Yeah, sorry I didn't include a debug node. I was wanting to get the timing right so it beats nicely. Do you think the basics of how I did it good?

The code is there, but hidden somewhere on the left halfway down. I probably didn't need to use that feature, but thought I'd try it. [Screenshot from 2025-07-06 18-28-47]

If it isn't working, then just remove the flows word so it doesn't try to render it - and add a comment to the original post about the flow viewer so we can track flows that aren't rendering properly.

(from my position) It works though I admit what I posted was/IS rather small so is hard to see/find. Which could be part of the problem. As I said, if I zoom OUT, go to the left and about halfway down: I see it ok. The last part.... Ok. Shall do. (Done.)

If you Zoom right out and then scroll halfway down it becomes visible. I have posted a comment in the original post suggesting that the flow may need to be normalised before viewing.
