Microcontrollers are a small computer integrated on a single chip. They are widely used in various industries and products from electronics devices to home appliances to automobiles.  Microcontrollers are required in the products and applications where small computing or logical operations need to be performed. So with this huge importance and demand of microcontrollers in industries, they are a prominent part of electrical and electronics studies.

There is a large number of semiconductor companies manufacturing variety of microcontrollers, the most popularly used ones are ARM microcontrollers, 8051 series, AVR series, Microchip's PIC microcontrollers, TI's microcontrollers, etc. Below section covers a list of simple microcontroller projects to learn and work with the concepts of various microcontrollers and architectures. These microcontroller based projects are covered with detailed explanation of working of hardware, circuit diagrams, software and codes.  If you want to see the projects based on microcontroller categories, check the project lists of 8051 microcontrollers, AVR microcontrollers, PIC microcontroller, Arduino, Raspberry Pi.
