hello Danny doxy here from how to mechatronics comm in this tutorial we will learn how to control high voltage electronic devices using the Arduino board we can do that using relays relay is actually a switch which is electrically operated by an electromagnet the electromagnet is activated with a low voltage for example 5 volts from a microcontroller and it pulls a contact to make or break a high voltage circuit as an example for this tutorial I will use these two channel relay module HL 52s which case 2 relays with rating of 10 amps at 210 and 50 and 125 volts ac and 10 amps at 30 and 28 volts DC the high voltage output connector has three pins the middle one is the common pin and as we can see from the markings here this pin is the one for normally open connection and the other one is for normally close connection on the other side of the module we have these two sets of pins the firs
