How to use ESP 32 with 5V Relay

This video will show you how to use 5V relay with Esp 32 and simply to control 12VDC solenoid lock but instead of solenoid you still can use any other appliance like AC light bulb or DC motors etc. I suggest you watch my previous videos how to setup Esp 32 with Arduino IDE in this link here;   • How to Setup ESP 32 with Arduino IDE Softw...   because you will need a few change before uploading the code.Thanks guys.
