Microcontrollers provide functionality and give intelligence to products and systems. From mobile phones to washing machines, many everyday products are controlled by these devices.
Purpose of process devices
Process devices take the signal from the input stage of a system and act on it by changing it in some way - for example, introducing a time delay, counting the number of times something happens or making decisions. Programmable components, such as microcontrollers, are often used for this purpose.
A microcontroller is an example of a SBC (single board computer) and is manufactured as an integrated circuit (IC). It can be programmed to perform different processing functions.
