Eric Escobar has a very neat Pi-powered solution to the problem of night-time chicken imprisonment, which is safer than some others we’ve seen, which use linear actuators. This door’s lowered using gravity, so there will be no very, very, very slow and eventually deadly crushing of any chickens or small children with Eric’s setup. The door is programmed to be lowered at a certain time of day, once it’s dark enough for all the chickens to have moved indoors.
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.
