What is a microcontroller?
Although you may not know, there may be many such things in your home! A microcontroller is an integrated circuit (IC) or “chip” typically used
in devices with electronic circuits installed in households. You may have heard of microprocessors, such as Intel Pentium, which are used as
the CPU (central processing unit) in computers and are actually the “brain”. A microprocessor is an integrated circuit used to process instructions
in computer programs, perform calculations, and send data to and from memory and disk. A microcontroller is a specific type of microprocessor.
It differs from ordinary microprocessors in the following aspects:
It has a built-in “I/O” (input/output) function. Therefore, it can read and write digital and analog values/states, and directly connect to the “real world”.
Unlike microprocessors, microcontrollers can be directly connected to switches, buttons, LCD displays, etc, LED， Relays and serial ports
Microcontrollers are typically used for specific tasks in devices with low to medium complexity. This is in stark contrast to the powerful digital processing
microprocessors used in PCs that handle various software applications.
Microcontrollers are typically used in portable devices that rely on battery power. Digital camera. Therefore, they typically have low power consumption
and low current consumption (unlike the cooling fans in desktop computers that cool microprocessors)
Compared to microprocessors in PCs, the RAM in microcontrollers typically ranges from 64k to a minimum of 1k.
