In this IoT project, I have shown how to make an IoT-based Home Automation project using ESP32 and the new Blynk IoT app to control an 8-channel relay module from the manual switch & smartphone.

LED Blinking is a very common and almost first program for every embedded learner or beginner. In which we blink an LED with some delay. So today we are here with the same project, but here we will ...

This project is an advanced 4-channel relay module designed for home automation and IoT applications. Unlike standard relay boards, this design integrates an LM2596 buck converter for onboard ...

In electronic and industrial automation systems, relay modules play a crucial role by allowing low-power control signals to switch high-power devices. Selecting between a 5V relay module and a 12V ...

IN - This pin is also called the control pin because it is used to control the output of the relay. COM - is connected to the device you intend to connect. NC - terminal is connected to the COM ...
