A microcontroller (also known as MCU) is a microcomputer system includes CPU, random access memory (RAM), read-only memory (ROM), various I/O ports and interrupt systems, timers/counters and other functions integrated into it. It is widely used in the field of industrial control.
What are Microcontrollers?
A microcontroller is an integrated circuit chip that is dedicated to performing a task and executing a specific application. It contains memory, programmable input/output peripherals, and a processor. SCM is mainly used for embedded applications. A large number of electronic devices are used for automatic control, such as mobile phones, cameras, microwave ovens, washing machines, etc.
Microcontrollers are electronic components and small computing engines that can be used in any application that requires decision-making or system monitoring. There are many microcontrollers available for integration into products. Microcontrollers usually have analog and digital input/output functions. Users can use various programming languages (such as assembly, C and C ++) to program the microcontroller. These software programs can be developed to monitor and obtain certain inputs, perform high-speed calculations and analysis, and generate outputs to control various devices, such as LCD screens, actuators, and so on.

What can MCU do?
1. Microcontrollers can be used from calculators to high-end complex (such as heart monitor) basic instruments. Almost all electronic medical equipment, such as blood pressure monitors, blood glucose meters and oximeters . They all have advanced single-chip microcomputers.
2.The complex electronic weapons used by the defense department also include microcontrollers. Anti-tank missiles, surface-to-air missiles, and some guns currently used by the military will be equipped with microcontrollers in their electronic circuits.
3. Electronic toys in daily life also include microcontrollers. Thanks to the integration of the microcontroller, the toys have become more interesting and have provided a huge educational platform for children. Mini robot toys, remote control cars, helicopters and airplanes are products that use a microcontroller.
4. Equipment used in the kitchen and at home, such as refrigerators, TVs, radios, washing machines, dishwashers and even humidifiers, all have a single chip microcomputer. SCM has great influence in improving the quality of our daily life.
