Story

After seeing a few extremely difficult projects involving automating games, I thought I'd try to make an easier and unobtrusive version using Arduino and tools on hand!

Concept, Build, and Demonstration Video

The device uses a stepper motor, motor driver, limit switch, rotary encoder, and OLED display.

When turning on the cups run through a homing sequence to find the limits of the AL2020 rail it slides on. Afterwards, you are able to select your difficulty 1 - 10 and start the motor through the menu displayed on the OLED screen.

The table is made from a sheet of 3/4" plywood and some 2"x2" used as legs. It also uses 1/4" thick acrylic at the ends to show the mechanism below the table, while keeping the entire top of the table flush and flat. Thus, you can use the table as a normal beerpong table, or as the automated version if supplied with power!

Schematics and circuit diagrams

Wiring Schedule for Components

Works with Arduino Uno and Nano. Needs 12V supply and 5V to power motor driver and Arduino, respectively.

Code for Automated Beer Pong Game

This is for the game, some adjustments might have to be made if using a different motor driver (TB6600) or motor with different degrees of steps.
