Arduino simplifies things by only using just one coding language. Here's what you need to get started with developing software for the tiny device.

You can see the straight key being pressed by a hobby servo in the image above. The servo is driven by the Arduino, which will transmit the series of letters automatically.

The sketch he’s using allows him to stream g-code to the popular prototyping platform, freeing him from needing a dedicated PC.

That said, the Electron is not intended to be a simple Arduino clone, and it does a very good job of incorporating cloud connectivity into sketch code with Particle-specific functions (sometimes ...

To make that actually work, Robofun paired an Arduino board with some capacitive controllers for the base, and connected that to a Raspberry Pi that linked the keyboard to the TV.
