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.

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 ...

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 - 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 ...
