For the last part of my Illogical Logic series I want to show how we can take what we have looked at so far and use it in one small project – to build a counter with a 7 segment display. For the last ...

We here at Hack A Day love LED’s, and all things LED related, but one of the biggest problems with LED’s are the small size. We want bigger and brighter, matrices the size of our TV, seven segments as ...
