For those worrying that [Faransky] is relying on the PWM functionality of the Arduino Nano to generate waveforms, have no fear. At the heart of the device is a AD9833 waveform generator ...

The PWM output pins on the two boards also differ ... it's a different story if you already have certain projects in mind. As the Arduino Nano and Micro cost the same ($24.90), deciding which ...

Relatively modern silicon such as the Atmega328 in [c0pperdragon]’s Arduino Nano Tetris console should ... and the audio is not the direct PWM you might expect but a very simple DAC created ...
