During my A-Levels, for my EPQ I decided to commence a project titled "To design a smartwatch and evaluate it against commercial alternatives.". This project was to design and build a smartwatch, using an ATMega328P chipset and the Arduino code. Due to complexity of the project, I was unable to fully build the watch, with the casing and bluetooth implementation - however bluetooth was printed on the circuit boards.
I do intend to reopen this project at a later date.
