Apart from understanding the Arduino's code language ... and D12. The PWM output pins on the two boards also differ, with the Nano having six (D3, D5, D6, D9 to D11) and the Micro having seven ...

The Pico also has more PWM output pins ... Other than the USB port, there are other ways to power the Arduino Nano. You can use an unregulated external power supply with a rating between 6 ...

A few months ago, [Julian Ilett] found a problem using the Arduino library for PWM. Recently, he revisited the issue and used his own PWM code to fix the problem. You can watch the video below.

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 ...
