Thanks Old_Grey, well I'm new to all this...
I built a breadboard prototype with an Arduino pro mini and a bunch of breakout boards ( two MPR121 capacitive touch breakout boards, a CH340G serial/usb breakout board and four AH180N hall effect switch breakout boards )
I got things working as I wanted and then I used the open source schematics for all of these to draw out schematics in Fritzing dragging in parts from the core parts library, searching for some sparkfun parts and creating some parts myself that were not there based on generic ICs and using the data sheets and package footprints.
I'm not sure what to do next then, I guess I was not aware of best practice. I thought I would just use these Fritzing parts selecting the correct values, and choosing package sizes according to my design. I was then hoping to source and buy the components. Surely all of the parts in the Fritzing libraries are buyable on Digikey? It's just there's so many things on Digikey and I don't know what to go for. What are your suggestions for my next steps?
( Meanwhile I'm building a toaster reflow oven for the assembly and soldering once I get the boards and parts )
