This project contains Arduino code for an ESP32 microcontroller to control a relay module, which in turn controls lights, to create a variety of blinking patterns. The code is designed to demonstrate ...

So, you can easily make this home automation project at home just by using a ESP32 and relay module. Or you can also use a custom-designed PCB for this project. Required Components ... This is the ...

The smallest quad-channel relay board I’ve seen so far is the one by Seeed Studio using an STM32 MCU and solid-state relays that measures just 60 x 40mm, but the relays only support up to 2A. ESP32 ...
