Final Project – Final Writeup

After yesterday’s exam, I have completed the Electronic Technologies program at Heritage College! Although final marks are not yet posted, graduation is certain, and I can pretty much call myself a Technologist (except not officially).

The biggest part of this third and final year was the final project. I’ve made a few posts in the past about it (video, menu, schematics), and the original plan was to make separate blog posts for each step of the process. However, time constraints, and the sheer volume of material, makes it easier if I just provide this summative post.

This post will be divided down into two main sections: hardware and software. I will try to explain with detail while keeping it short, and cover some of the key elements and choices involved in making this project.

Final Project – Walkthrough

After two semesters, I can finally present my complete, ~fully functional, Final Project.

A good project is never finished, and I do indeed have other features and fixes I would like to implement in the future.

Check out the video below to see it in action!

Final Project – Menu System!

Over the winter break I didn’t do any work on my third year project, though I told myself I should. So, when the semester began, I was at the same stage as before the break:

  • Real-Time Clock functional
  • Relay triggering functional
  • Changeable target temperature with buttons
  • Status display on LCD

A menu system is completely necessary for a thermostat of this complexity; options to change backlight colour, configure the time, modify schedule, and others, can only be practically configured through a menu.

This was the result of an hour or two of work:

Look past the break to also see a video demo of the menu interface!

Build Journal – Final Project – Schematic

Over the next little while I will bring you through the processes of engineering my final project. From circuit design, prototyping, PCB layout, hardware manufacture, programming, and final packaging, I will give you a commentary on my choices, and what I might have done differently. Hopefully you can learn something in the process!

Before we get too far ahead in the project, let’s start at the beginning.
