+The examples below may be used as a tutorial. Every example is a complete Arduino sketch. It was decided to use Arduino boards for examples because the boards have somewhat standardised application programming interface and hardware.
 
 Nevertheless, this library can be used on its own on AVR controllers: it does not contain any Arduino-specific code. Hopefully, the examples are easy to adapt to any AVR based hardware.

 This example demonstrates how an asymmetric coroutine might be used as a generator. Every time the coroutine gets invoked it generates the next number in sequence (`0...N`) and returns it back to the invoker.
