In this video, we demonstrate a DIY home automation project using a NodeMCU and a 4-channel relay module, integrated on a custom PCB. This project is perfect for anyone interested in IoT (Internet of Things) and home automation. We'll guide you through the process, from designing the PCB to coding the NodeMCU, and finally, testing the system to control multiple home appliances. Whether you're a beginner or an experienced DIYer, this project is a great way to get hands-on experience with IoT and home automation technologies.

Watch us walk you through step-by-step custom PCB assembly, which eliminates the need for bulky jumper cables and provides a neat, reliable setup. We'll also cover the coding part using the Arduino IDE, showing you how to connect the NodeMCU to your Wi-Fi network and control the relays via a web interface.

This project is a great introduction to the world of IoT and can be a great addition to your smart home setup. Stay tuned, hit the like button and subscribe for more exciting DIY projects!
