Embedded systems are a very important element contained in the design of many contemporary physical applications, such as home automation, industrial processing in factories, measurement instruments, vehicles and machines, games and toys, household appliances, as well as communication devices and information systems. In most of the embedded systems, a fundamental element is a microcontroller - an integrated circuit, which, like a microprocessor - reading data from memory and executes a set of instructions contained in the program source code that is stored in a non-volatile memory. A typical microcontroller usually has lower computing power than a microprocessor, but is capable of autonomous operation thanks to the built-in memory and peripheral systems. One of the leading manufacturers of microcontrollers is the Microchip company. In 2016, Microchip Technology Incorporation have acquired Atmel Corporation, known for its AVR microcontrollers, such as Atmega328p used in Arduino boards, which are still being manufactured under the Microchip brand. In addition, Microchip also offers genuine series of PIC microcontrollers built into the development board. It is a versatile tool with which you can learn the basics of microcontrollers hardware and software operating, as well as making of prototype designs of control systems for numerous physical processes, such as electric gate controller or DSP systems for an advanced sound processing.
