Pic microcontrollers, for beginners too online, author. A cars microcontroller in alaska has to work fine in 30 degree f 34 c weather, while the same microcontroller in nevada might be operating at 120 degrees f 49 c. However, it does not store the data permanently and its memory is lost once the power supply to the microcontroller. Microcontrollers are embedded inside devices to control the actions and features of a product. For example, the microcontroller at work in your car likely has to deal with temperatures anywhere from 30f in a winter in alaska to something as scorching hot at 4f over in death valley in the peak of summer. The microcontroller controlling a cars engine, for example, has to work in temperature extremes that a normal computer generally cannot handle. Like traditional computers, microcontrollers rely on different features to get their job done. If the file has been modified from its original state, some details may not fully reflect the.
