So I want to add some kind of visual indication that my main arduino loop is still well, looping. I decided on an LED “spinner”, kind of like on web pages and applications. but how to do it?
After a lot of searching I found something neat. A decade counter.
Seems this nice little IC (4017) has 10 outputs that go high in a sequence when given a pulse. The perfect thing to do when you want LEDs to “chase” or spin.
I hope to add this to the new LCC. Should help indicate that the main loop is still looping!
