Ringing a bell, throwing some cash, snapping your fingers and maybe even showing a little extra cleavage have all been used to flag down bartenders. But Sean Carney, creator of Barbot, can catch the attention of his bartender with a quick click of the mouse and a remote Internet connection.
The Barbot is an Internet-controlled liquor-dispensing robot that can mix a drink with up to five different ingredients. It offers a web interface that lets you know what ingredients are available, generates a list of potential cocktails that can be made with those ingredients, shows user ratings, and offers links to order a cocktail. Once you order a cocktail, it gets to work and can make you a drink in seconds!
After inputting your drink order, the Sitara-processor-powered BeagleBone Black controls three dual-H Bridge motor drivers, which are connected to peristaltic pumps that dispense the correct liquids into your glass. BeagleBone Black is connected to a USB Wi-Fi adapter so that you can order your drinks wirelessly. The computer runs Ubuntu 13.04 with Apache2, MySQL and PHP, bind and dhcpd installed. Apache2, MySQL and PHP are used to host the web interface, while bind and dhcpd create the Wi-Fi portal. The web server directly controls the pumps by using PHP to write into the GPIO sysfs files.

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.
