The objective of this project was to develop a breathalyser device based on a programmable microcontroller chip (ATMega328). This development also included design and manufacture of a custom Printed Circuit Board and fabrication of an enclosure for the whole system cut from acrylic glass material. The breathalyser system was developed to include additional features (such as a Highscore table) and provided a simple and user-friendly interface. I found this to be a particularly valuable exercise in acquiring insight into embedded systems development, not to mention having the most rewarding validation experience of all projects.
