Foolios:
I want to transfer my project from my breadboard to a printed circuit board.
Will the locations on the headers that I have wires plugged into on the arduino uno line up exactly with where I want to solder my wires to on the circuit board? Can I just take where a location is for a wire in the header, say Analog In Pin A4, which lines up with the second leg from the end of the microchip and solder it into the second hole location that lines up with that same leg of the chip when I transfer it over to the circuit board as well?
Or do the pins in the header not line up with legs of the microcontroller? Do they cross at all? I ask cause I've been searching pinouts and all I get are photos of the board, not any schematics of the chip itself.Thanks in advance.
There is no direct relationship from chip pin numbers and arduino defined pin numbers. you must use a proper mapping drawing to show you how to wire up a standalone chip. The below link will show you the mapping from the red Arduino pin numbers to the chip numbers next to the chip. Note that a 328p chip has the same pin out as the 168 chip shown:
