Eric's Arduino Breathalyzer

This is the basic Arduino code I set up for using the MQ3 Alcohol Sensor.
This is NOT a certified or calibrated method of detecting alcohol content. Use at your own risk.

Remember you need to install the Adafruit libraries for the OLED sketch mentioned here: include Adafruit_GFX.h include Adafruit_SSD1306.h

You can’t perform that action at this time.
