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.
Cricket provides an easy way to add measurement and action to a project. Adafruit IO provides an easy way to collect data from devices, make some basic decisions based on it, and communicate back to devices. Putting them together by using a Feather with network capabilities opens the gates to some interesting possibilities.
