These products achieve intelligence functions and properties. Microcontroller is as low cost embedded system and it is almost every time hidden in product and normal user never sees it. Possibilities of microcontroller are limited, but there is a possibility to make group of microcontrollers and many tasks can be divided between these microcontroller. It is something like computer network and controllers can cooperate with each other. http://pubs.sciepub.com/automation/4/2/5/automation-4-2-5.pdf embedded systems microcontroller communication interface
