Les Kelly first showed off his gadget skills in Gadget Freak Case #178, where he created a device that let his dog out of a crate remotely. Now Les has taken the show outdoors with his Easy/Out! remote trigger. Les believes the application for Easy/Out! goes beyond home pets to kennels, chicken hatches, and other livestock containment. The trigger works through walls, floors, and other obstacles with a simple push of the button.
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.
