Interrupts 101 - All About Arduino 4

Описание: Interrupts are part of everyday life. This is equally true for computers - including embedded systems such as Arduino.

Computers rely on interrupts for smooth operation. In this video I have a look at interrupts on Arduino including what they are, how they work, real world examples and some simple follow along projects that explore them.
