Our Project
The Barduino is an automated drink mixing machine. There are five buttons, each corresponding to a different mixed drink. When the button is pressed the BARduino starts to make the drink. For each ingredient, the corresponding solenoid valve is opened so the liquid can flow. The ultrasonic sensor repeatedly measures the distance to the surface of the liquid. This distance is converted to fluid ounces using a linear regression curve, obtained by plotting specific fluid levels. When the specified level is reached, the solenoid closes. Currently, a large measuring cup is used to catch the fluid; drinking glasses are too narrow and create an echo which disrupts the ultrasonic sensor readings. Below is a video of the BARduino in action.
Motivation
We decided to create BARduino in order to take the human error out of cocktail mixing. All too often, people complain about receiving drinks that are either too strong or too weak. Once we complete BARduino's construction, we hope to eliminate the problem of the poorly mixed drink forever!
