As part of the hardware project for grade twelve computer engineering, my friend and I had decided to make a thermal jacket that is designed to keep the wearer comfortable when it gets too cold. The thermal jacket is uses an Arduino board, which is powered by batteries, that would check the outside temperature using a temperature sensor, and if it is too cold, it will activate the heating pads that would warm the wearer.
