In the recent decade, microcontroller project has increasingly become a norm in the lives of students, teachers, home appliances and controls designers. It has evolved from 4 bit to 8 bit to 16 bit to 32 bit as more and more powerful silicon processes are put in place.
As the years gone by, the price of MCU has dropped by more than 50% making it a common device that is chosen over the more traditional analog type of circuitry. These days, it is not uncommon to find that the overall MCU based solution is much cheaper than its analog counterpart.
Some of the tips and methods of using MCU as well as some constructional projects are listed below.
