You're a human! Right? For now anyway... There's a red pulsing in the distance... NO! A ZOMBIE! You're losing health, but what's this? A white pulsing from around a corner, a healer! You'll stay human for a little longer... We've written up a fun game for you to play with Circuit Playground Express and CircuitPython or MakeCode. Hopefully you'll be a human long enough to check out this guide!
GBoard is an alternate keyboard for Android Devices that lets you type using Morse code. This has seen use for people with limited mobility, but it can also be useful for practicing your morse code skills. The goal of this project is to build a simple input device for GBoard that doesn't require soldering or elaborate construction techniques. We'll be using a Circuit Playground Express to build this project. We have a few different versions we'll be demonstrating - from the simplest using the two onboard buttons, to using capacitive touch inputs, to connecting up some alligator clips to big-and-easy-to-press arcade buttons.
Circuit Playground Express has the ability to transmit and receive IR signals. You can use CircuitPython to send and receive messages using IR. This guide covers the basics of Circuit Playground Express IR and shows you how to use CircuitPython to communicate between two Circuit Playground Expresses!
