EDIT - UPDATED CIRCUIT DIAGRAM
I'm looking for some guidance in implementing an Arduino Uno controlled system that I have had success with, on an AdaFruit Perma-Proto board using the ATMEGA328p to reduce the spatial footprint and hopefully durability (particularly of my connections as I can use screw terminals).
I have basically outlined the project here;
With my main question and uncertainty being the layout and structure below;
Basically I'm just wondering if anyone with experience in creating an embedded circuit like this could have a look at the breadboard diagram to confirm that it will actually work before I start soldering.
