GAEYAELE 2 Channel Relay Module AC/DC 12V 24V AC232V Relay Interface

My name is Ahmad Shamshiri. I am presenting this tutorial from Canada. Hi, welcome to Robojax. in this video we are going to see how we can use this 2 channel 5 volts relay for Arduino to control an AC load and a DC or maybe with the combination of both ACE or both DC like this. now the load will be on and then the motor will be on alternatively in mind that when you are connecting this to AC load do not touch this area or this area if you're working with this you have to have proper protective gloves and also make sure that you do not leave it on a surface that is metallic or conductive so this is a relay the size you can see it in my hand we have to relays each relay has these three contacts so these three contacts belong to this relay and this relay has these three contacts these contacts are named as normally closed (NC) this and this so if you connect a wire here and here it will b
