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

In this tutorial we are going to interface a rotary encoder with ATmega8 microcontroller. ATmega8 is atmel’s microcontroller series designed for embedded applications. Rotary encoder is used to know the position of movement and angular movement of a motor or axis. It’s a three terminal device usually, with power and ground pin counts to five. A rotary encoder

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

An implantable, microchip-based device may soon replace the injections and pills now needed to treat chronic diseases: Earlier this month, MIT spinout Microchips Biotech partnered with a pharmaceutical giant to commercialize its wirelessly controlled, implantable, microchip-based devices that store and release drugs inside the body over many years. Invented by Microchips Biotech co-founders Michael Cima, the

Summary The solar energy collection is not that easy compared to the different types of power generation system because it has the lowest capacity factor. It has 5 out of 24 hours in a day that it can generate electricity from its solar collection. The only solution to this is by optimizing the 5 hours
