This past semester I’ve been working on a directed study at my university with Prof. Wil Robertson reverse engineering embedded devices. After a couple of months looking at a passport scanner, one of my friends jokingly suggested I hack a Furby, the notoriously annoying toy of late 1990s fame. Everyone laughed, and we all moved on with our lives.
However, the joke didn’t stop there. Within two weeks, this same friend said they had a present for me. And that’s how I started reverse engineering a Furby.
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.
