“This is the story of how I taught myself soldering, coding, and machine learning, all to thwart my sweet murderous cat.
He brings in dead (or not dead) rats, mice, and birds. I tried to stop him with bell collars, operant conditioning, generous feeding. Nothing worked. So I built an AI-powered cat door that can tell when he approaches with a critter in his mouth. If it’s just the cat, door’s open! If he’s carrying a rat or bird? Cat door locks, texts me pics, and donates to bird conservation.”
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.
