Our first experiment was to hook up a liquid flow meter to a Raspberry Pi and have the keg tweet every time someone drinks from it! Follow @AdafruitKegBot for updates.
For now the keg has birch beer, but we’ll be getting a beer beer kegerator soon and will mod that one up as well! Post your feature suggestions in the comments.
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.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7:30pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
Have you found the beer to be foamy since installing these flow sensors? We had good luck with swissflow flow sensors but these types of sensors introduced lots of foam.
