Digital Tap Handle

This system is a digital tap handle that is used to count the pours from a tap. The main goal of this device is to provide bar owners with data about tap usage and prevent free drinks from being given out. One key feature of the system is that it can be charged wirelessly, which helps to make it water-resistant for the bar environment. Our main components of the projects are the accelerometer and a microcontroller used for Bluetooth transmission. The accelerometer is used to determine the position of the tap handle, while the microcontroller collects position data and transmits it via Bluetooth Low Energy to the Raspberry Pi software hub. This software hub will receive the position data from multiple tap handles, then send it to the Pour Soul Systems server. From there, the position data will be converted to pour count data with the code they’ve already developed. The most notable accomplishment was that the PCB design worked the first time. Implementing the Bluetooth functionality proved to be the biggest challenge. One main area of improvement we would like to see is moving away from prebuilt modules and implementing unique, onboard circuits for all the components.
