Asset Overview
This file links to a complete project, from the design to the electric scheme, from the PCB to the 3D-printed container, I published on Hackster.io
Our article concerns the design of a breathalyser: we will study the concept, the choice and calibration of the sensor, the addition of a buzzer and finally the use of an LED bar. We will see how to produce the electrical circuit and the pcb, and a container that we can build using a 3D printer or plywood.
