AudioFrequencyMeter Library for Arduino Allows the Arduino Zero and MKR1000 to sample a generic input audio signal and get the fundamental pitch.

The audio amplifier has a volume control, and the inputs and outputs can be selected via button presses. An Arduino Pro Mini takes care of switching the relays based on the button presses.

Meet the Production-Ready Arduino Compatible HQ record and Playback Audio Module! With ease, you can record and playback up to eight sound bytes using your own voice, or PC.

It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than others. For example, ATmega328P (Figure 13-2, Arduino Uno and Nano) and ATmega32U4 (Figure 10-2, Arduino ...

I had cause to have a closer look at some Arduino inputs – it is that fascinating weather station again. It transpires that some Arduino inputs are better at tolerating slowly-changing inputs than ...
