mikroohjainjärjestelmät

mikroohjainjärjestelmä is a Finnish term that translates to "microcontroller system." A microcontroller system is a complete computer system built around a single integrated circuit, the microcontroller. This microcontroller contains a processor core, memory, and programmable input/output peripherals all on the same chip. They are designed for embedded applications, meaning they are part of a larger system and perform a dedicated function.

These systems are ubiquitous and can be found in a vast array of electronic devices. Examples include household appliances like washing machines and microwave ovens, automotive systems such as engine control units and anti-lock braking systems, industrial automation equipment, medical devices, and consumer electronics like remote controls and toys. The low cost, small size, and low power consumption of microcontrollers make them ideal for these embedded roles.

The design of a microcontroller system involves selecting the appropriate microcontroller for the task, along with any necessary external components such as sensors, actuators, power regulators, and communication interfaces. Software, often referred to as firmware, is programmed onto the microcontroller to define its behavior and control the system's operations. The development process typically involves hardware design, firmware programming, and thorough testing to ensure the system functions correctly and reliably. The versatility of microcontroller systems allows for a wide range of control and automation capabilities in diverse applications.
