 ==== Technical details ====
-This laboratory consists of a relay module attached to the ITT IoT controller module. Relay module is an electrically operated switch of mains voltage. It means that it can be turned on or off, letting the current go through or not. Many relays use an electromagnet to mechanically operate the switch and provide electrical isolation between two circuits.
