audiogetavarage is a simple library you can use to interface with an audio input. It reads data from an ADC pin and returns the RMS value of the input simply using rms avarage. The root mean square (abbreviated RMS or rms), also known as the quadratic mean, is a statistical measure of the magnitude of

For my monthly maker column in Dutch newspaper “De Volkskrant”, I made a coolbox in which you can control the temperature in three separate compartments to keep craft beer at just the right temperature. The contraption I build uses three Peltier-elements to cool, an old desktop computers power source, an LCD to show both the

Choosing components is a series of time-consuming tasks, from surveying the market for possible candidates to properly evaluating performance. As a hardware engineer who has worked in Silicon Valley for 10 years, I have spent significant time developing test plans and specs, building fixtures, and testing components. One of the reasons comparing components takes a
