Auto Switching to Battery Module l Power-off Switching Module l Modem/LED Protection Switch-over.

Hello Friends, Welcome Back.
In this video, we will see how to make a module for our modem/router/LED for continuous connection. I have made an Automatic Switching Module with Relay. I made this module after so much research and finally, I got the best performance. As I said this is my own creation so, if you find anything wrong/need to change in this module, Please comment. Because I am not an electronic professional.
