Arduino Breathalyzer Project using MQ3 alcohol sensor 0.96' 128x64 OLED display on Arduino Mega
Welcome to another Arduino project video! Today we are going to build an Arduino Breathalyzer. It is a device that senses alcohol in the air and prints the value it reads on the display. We use an MQ-3 gas sensor along with an I2C OLED display on an Arduino Mega. It is a very easy project to build, it won't take us more than 10 minutes. There is a lot to cover so let's get started!
