How to not use Arduino
First off, I would like to apologize if this has been explained before, but I cannot come up with any search combinations leading me to my answer. So, here goes...
I have completed a simple project using an Arduino Uno and breadboard. I then drew this project in Fritzing. I would like to get a PCB made of this project, but would like to keep the form factor small. My question is, how do I take the Arduino out of the equation? Would I have to replicate all the components on the Uno board into my custom PCB in order to drive it? Or, can I get away with just using the ATMega IC on the PCB for the "brains", and then try and figure out which pins I need to solder to?
My project is here: http://fritzing.org/projects/lightning-trigger-for-nikon-dslr-camera/
I would like to not have to purchase another Arduino to be permanently connected to the PCB, but do not know how to go about it.
That is perfect! I definitely appreciate your help!
