4 Digit 7 Segment Display With Assembly via using PIC16F84A
I used below information while making the circuit
I have also tried to make it in real life but due to some problems with copper plate and since It's a two layer pcb which is hard to heat the copper plate with an iron I couldn't manage to make it.
It supposed to look like this but as I mentioned before
It looks like those
Note : I might have fix the problem but 2 layer copper plate is very expensive and I spend all my money to pickit3 :/
