For the Bay of Plenty Science Fair, the 14-year-old Bethlehem College student designed and built ‘Gran Check’, a Raspberry Pi-powered monitor that uses a PIR sensor to recognise his gran’s movement as she feeds her dogs, taking a photograph every morning to email back to his mother.
The Gran Check lives within a wooden box, installed beside his grandmother’s dogs’ food. He knew it was the best location, since the dogs would never allow her to go a day without feeding them. For added peace of mind, James built the device to be self-sufficient, ensuring she’d never have to operate it herself.
James noted his grandmother’s independent nature, understanding that constant ‘check in’ calls from the family would be unrealistic. The Gran Check removes all concern for her welfare, without constantly bugging her for updates.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
