Decade Counter!

I wanted a way to have a “rotatable” counter to indicate that the LCC was still looping properly.  I finally found something! A decade counter (as noted in an earlier post)!

Now instead of pulsing one led I have a “spinner” type of effect. I don’t have to keep track of where the “count” is….I just pulse it. Coding this would have been a nightmare. Of course wiring 10 LEDs is a mess but it’s a cool one.

LED Spinner!

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!
