When you just need one button, then you need the Adafruit NeoKey Trinkey. I can see a lot of use cases, including making it mute your audio, run a macro, or simply relocate your Escape key. The board comes populated with an RGB NeoPixel and a SAMD21 that can easily run CircuitPython or Arduino code, so it’s capable of doing a lot!
It’s specifically designed to allow you to add a Cherry-MX compatible mechanical switch and keycap (purchased separately). Or you could just use the on-board capacitive sense pad. Just slide the board into an unused USB port on your computer and it will power up and can be programmed.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
