Control the Gboard Morse Code keyboard with two switches
The DIY Assistive Switch Adapter for Android is a part of that Morse Code effort.
Many people cannot use keyboards and touchscreens to control their digital devices. Instead, they use custom hardware switches that emulate typing, swiping, and tapping. The Android operating system provides software that allows these switches to control Android devices, and recently Google provided a new Morse Keyboard within the Gboard keyboard for people who find this method easier for text entry.
This experiment is a DIY hardware adapter that enables assistive tech developers to connect existing switch based input systems to their Android device. Once connected, 2 switch assistive systems (with an additional switch for mode switching) can control both the standard Android accessibility functions as well as text entry through Morse on Gboard.
This experiment is built using Arduino and is compatible with most standard assistive 2 switch systems with ⅛” mono outputs.
