Hi, I am trying to interface PIC16F88 with 8x8 LED MATRIX, using 4017 and ULN2803. My aim is to built a binary clock, and before directly jumping to hardware I thought of doing the simulation on Proteus 8.1 .
So I interfaced the components and wrote the Embedded C program for the binary clock and tried to run the simulation on my computer, which as you have already guessed, didn't worked.
The main problem is ULN2803, it is not sinking current(i.e. there is no current flow on the right side of ULN2803)
Can Anyone please look at my circuit and tell me whats the problem there.
Thank you.
