Das Bot is a system for monitoring and controlling access to beer through RFID tags. Built on top of an internet-connected Arduino, the system accepts an RFID tag, checks to make sure you’re registered, opens the solenoid valves in the beer lines, lets you pour a beer and monitors how much you’ve poured, saves the data to a database, and prints out a receipt. Oh, and there’s prize badges you can win as well. There were three beers on tap this year (a homebrewed Dunkelweizen, a homebrewed Hefeweizen, and a Hofbrauhaus Oktoberfest) and each beer was tracked independently.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
