Did you buy a flat cable for PIC circuit ?
Do you know an electric circuit flat cable ?
No.1 - No.1 connection cable in flat cable is an another color, Red, White, etc,.
We use White jumper cable for No.1 pin of IC Data bus on our PIC Breadboard circuit.
This is the simple and useful.
We do not need to watch datasheet to find out No.1 pin of IC Data bus.
White jumper cable is for Clock too.
Because The House of Shirose is called 'Clockwork'.
