Interrupts in Teaching Microcontrollers Using Arduino

The paper summarizes the mechanism of event servicing through interrupts in the embedded systems design - one of the most complex and abstract topics in microcontrollers and embedded systems disciplines. Some special features of Arduino IDE, relating interrupts, are given. It is also briefly presented how a smart home model is used as a suitable complex object to study microcontroller interrupts, among various hardware and software aspects of embedded system design and programming.
