This project is intended to be a predecessor to my Major Project.
It involves some, but not all, of the elements of the Major Project.
The Minor Project tests the temperature environment inside my fridge, to get an idea of the temperature range involved, & possibly how much scaling of output values from a thermistor will be needed.
The thermistor will need to be evaluated as regards its temperature range, & also what value of pull-down resistor (if any) will be needed.
A photocell-driven Interrupt sequence will be included, to record when the door is opened.
