Tired of being wrongfully accused of passing gas?
Join me as I embark on a journey to settle 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, we turn my dog’s favorite animal plush into an animated fart detector with Arduino, color-changing LED lights, twitching nose (micro servo) and gas sensor on an extendable tail.
No one ever believes it was the dog – until now!
