Fart Detector Arduino Wiring + Code

Join me as I embark on settling the age-old question: Did “he who smelt it, dealt it?” By investing dozens of my dollars, using a few electronics and a bit of science, let’s build a working fart detector together!

We’ll go through how to wire a gas sensor and 3 LEDs together along with some easy Arduino code to detect 3 levels of stinkdom. Once we have a working fart detector we’ll need a way to package it. Should we use it as a hand-held detector or disguise it in an everyday object and leave it in plain sight?
