Step 3: START TO PROJECT
First of all, as you can see in pics, you have to put in all jumpers. And next step...
Step 4: Resistors and IC Sockets
You can see details on pics and PCB layouts and material lay outs. This schematics will help you. Firstly, you use resistors. and than ıc sockets.
Step 5: Displays
And the last step, put Displays. And go...
Step 6: Hex Code
You can find Hex code for clock. Send to your PIC.
