+Denko doesn't run Ruby on the microcontroller (see the [mruby-dino](#mruby) project). It runs a C++ firmware that exposes as much low-level I/O as possible, so we can use it in Ruby. It becomes a peripheral for your computer.
 
 High-level abstraction in Ruby makes hardware classes easy to implement, with intuitive interfaces. They multitask a single core microcontroller, with thread-safe state, and callbacks for inputs, but no "task" priority. If you need more I/O, integration is seamless. Connect another board and instantiate it in Ruby.

 **Note:** If using Ruby in WSL on Windows, you can follow the Mac/Linux instructions, but it is not recommended. Serial (COM port) forwarding isn't currently working on WSL2, which would make it impossible to communicate with the microcontroller. There are workarounds, and you might get it working by switching to WSL1, but the [RubyInstaller for Windows](https://rubyinstaller.org/) and Arduino IDE are recommended instead.

 Before using the microcontroller in Ruby, we need to flash it with the denko firmware (or "sketch" in Arduino lingo). This is needed **once** for each board, but future denko versions may need reflashing to add functionality.

 Denko uses Arduino cores, which add support for microcontrollers, and a few libraries. Install only the ones for your microcontroller, or install everything. There are no conflcits. Instructions for supported microcontrollers:

 ## mruby Port
 
 A single-board computer plus microcontroller can be a great standalone solution, especially if your project needs the computer anyway. For example, a Raspberry Pi Zero and Arduino Nano combo, running CRuby, Denko and other software.
