Check out Ben’s amazing cat-tronic project to turn feeding his cat into a game of hide and seek. By embedding small NFC tags into plastic balls Ben is able to train his cat to ‘hunt’ for the balls around his home and return them to a feeder. When the feeder detects the ball is nearby it dispenses food and rewards the cat for finding the ball. The project is built with Adafruit’s PN532 NFC reader and an Arduino connected to an automatic feeder. Check out Ben’s blog post for all the details on the project–awesome work!
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.
