A Guide to:
Microcontrollers
What is a Microcontroller?
A microcontroller is a “simple computer” that runs one program in a loop.
They are designed to perform a single, specific task, over and over.
Is a Raspberry Pi a Microcontroller?
A Raspberry Pi is a fully functioning computer, consisting of both Microcontrollers AND Microprocessors. They provide similar options to microcontrollers, but are additionally equipped with an Operating System, a user interface, hardware Input/Outputs, USB storage and more. Raspberry Pi’s are often used for more complex applications.
How do you use a Microcontroller?
The microcontroller is programmed using a coding language like Make:code, Arduino IDE, or Micro-python. Microcontrollers are used in our everyday life from garage door openers to air conditioning units.
