Smart devices can be smart without using a computing device, but they are obviously limited in their functionality without having the computing power to drive the inputs and outputs of the device. As you have seen from our first experiments with circuits, without an MCU to drive them, they can perform some basic functions, and provide a certain level of interaction. Aside from using a preprogrammed sensor or device with some logic already built-in, the ability of a circuit without an MCU to be truly “smart” is obviously heavily stunted. There are many considerations ...
