Hardware
Overview

The hardware that went into the project came mainly from our kettle device. In all, we used a water filter, 3D printed parts, an aluminum can, bolts and screws, a heating plate, a circuit board, electronic elements such as LEDs, resistors, a temperature sensor, and a microcontroller. All these components were either bought or manufactured to create our final design. Below you’ll find the specifications for the main hardware used.
