new relay module

Hello, guys today I am going to teach you How to make a Relay module with Optocoupler. Here I will explain everything to make a perfect relay module with an optocoupler.

All are we know the applications of relay module. When we make any smart project on home appliances, that time we use relay module most of the time. So if we are going to buy relay module form the local or online market, we have to pay huge amount of price according to home made relay module. So this article will helps you to make a sucessfull relay module witrh optocoupler.

Here you will get electronics related all information and electronics project making ideas with full guide.

If you want to see to make by me just comment down below I will definitely make for you guys.

Relay module Making Process

Now I am going to tell you how you can make relay module with just three simple step at your home. just follow the below three steps and make your relay module very easilly.

First Step to make a relay module with Optocoupler

The first step, you have to do is, Insert all the required components inside the Vero PCB. I have attached the picture of insert all the needed components to make a relay module. Scroll down and see that image of how to insert all the components.
