Hi Urs,

I've added some colors to the raduino schematic. The black/brown/orange/yellow of the encoder is on top, and while the speaker wire is also brown, I've colored the cw_tone trace purple. It's probably not great to drive the speaker by itself directly from the microcontroller, since it has such a low resistance, so if you can throw a 125k resistor in series with the speaker to limit the current on the D6 pin to 40mA, your nano will thank you.
