In Arduino we have 2 main functions the setup() and the loop(). Interrupts interrupt code execution in the loop(). But why should we care about interrupts anyway? They are not something to be feared, they make your code cleaner… Read Article →

You can download our e-book ‘Learn Arduino’ from this link In previous lessons we used the digitalWrite to write to a pin or more precisely to switch a pin on and off. That is the simplest way of using a pin. In this lesson we will go though reading and writing values to pins both digital and analog. So we need to settle somethings straight before we proceed here.
