When walking through Shanghai, or other cities in China, there is one thing you will see in many shops, restaurants and other places: the Maneki Neko, also known as the beckoning cat. Most of them have a mechanism in them, which lets one of their arms (usually the left one) move back and forth endlessly. A while back, a few friends and me were joking about what people would do when all the sudden, instead of going back and forth, the cat’s arm would start moving sideways. The idea had been stuck in my head ever since then, and now, we’re about to find out. So, let’s hack a beckoning cat.
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.
