Any die-hard Harry Potter fan will remember Neville Longbottom’s Remembrall. This object is described as a small, glass ball that fills with red smoke when its owner has forgotten something. Unfortunately, the Remembrall doesn’t inform the owner about what they have forgotten, rendering the item fairly useless.
Because I seem to have a knack for creating useless things, I decided to create a Remembrall that ACTUALLY WORKS!!!!! This Internet Connected Remembrall functions alongside Todoist, which is a web and mobile to-do list application. After gathering the owner’s data, the Remembrall turns red if due dates of uncompleted tasks have passed. While I will admit that my Remembrall isn’t quite as useless as Neville’s, it is sure to leave it’s owner in a state of panic as they try to figure out what they have forgotten (or at least I hope it does!).
HAPPY HALLOWEEN! Every day this month we’ll be bringing you ideas and projects for an Electronic Halloween! Expect wearables, hacks & mods, costumes and more here on the Adafruit blog! Working on a project for Halloween this year? Share it with us on Google+, in the comments below, the Adafruit forums, Facebook, or Twitter— we’d love to see what you’re up to and share it with the world (tag your posts #ElectronicHalloween). You can also send us a blog tip! Tune in to our live shows, 3D hangouts with Noe and Pedro and Ask an Engineer, featuring store discount codes, ideas for projects, costumes, decorations, and more!
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.
