This is sort of a follow-up to about three other threads, so rather than add it on to one of the three, I decided to start a new one. The link is to a video of my "Rube Goldberg" 16F84A "development board" with a plug-in daughter board that contains 13 LED's being driven by the 16F84A in a back and forth chaser pattern. Twelve of the LED's are being driven by 2N2222A switches on the daughter board. The other LED is connected to a 2N2222A on the development board that enables RA4 to be used as an output. I'm sure someone else has made a 13 LED chaser using a 16F84A, but I haven't seen it.

Here's the video. http://youtu.be/fgLskZgnC9M

 

Hey it works!!!

Good job.

 

Looks very nice. Bravo!

With all the bird songs in the background it sounds more like you're in a tropical rain forest rather than Tennessee.

Regards, Mike

That's actually our Tennessee state bird: the mockingbird. And you might hear a little thunder. It was just before a rain.
