Decade Counter For LED Matrix

Hello all. Back again. I have decided to use a HCF4017B (HCF4017BE) which is a counter. Its actually simple to use alone but when daisy chaining (cascading) it gets funny heh…

I am using this because the new board has 4x 5×7 LED Matrixs meaning there are now 20 rows to control. Using 3 4017’s i can control all 20 with 1 pin from PIC Micro. Which not only saves me PIC PINS it also simplifies coding since i can use a simple loop now.

Below you will see a video of it in action. I recommend going to youtube by clicking the video this way you can see a bigger HD video. The video will show how the 4017 (counters) work. And how i plan on connecting them.
