In the United States and across the world, alcohol has posed severe health threats when consumed in an irresponsible way…The question for this project is as makers, how can we address this problem and make sure fun celebrations with alcohol like parties can stay safe and fun?
My answer to this question was to find a way to estimate and then visualize the predicted BAC of the user to allow them to better understand what state they were in. For this project, I used the Arduino microcontroller with a water-level sensor, LED ring, and an LCD screen to track how many drinks a person has consumed, and then to find a way to estimate the blood-alcohol content (BAC) of the user based on sex and weight. The estimated BAC, depending on what range it was in, determines the animation of the LED ring below.
