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!
