# IOT Project Raspberry Pi Node JS GPIO Control Node JS + Express

How To Control Raspberry PI GPIO using Smart Phone - Internet of Things. In This IOT article, we will create one raspberry server in node js and control GPIO of raspberry remotely within the local network using smart phone or PC.

Steps:
1. Download code
2. Install node js on raspberry pi
3. install library using npm isntall
5. open browser and type url of raspberry pi along with port number

You are wicked clever. I live in Campbell California Silicon Valley and do land surveying and I'm trying to get into robotics thank you for all your videos man you're smart dude

Seems more like a demonstration than a tutorial. It would be better if you explained the code so that we can understand how it works and build similar, but different things ourselves

The tutorial is good. Pls remove annoying background sound .

What is a good way of implementing a listening service on multiple Pis to control the GPIO pins according to commands issued over ethernet?

To be clear, I intend to have a bespoke program / web page on a windows or mac machine that takes commands through a GUI, such as button presses, to control multiple Pis on the same network.

For example, 'click this button to turn on red LED on Pi 6', or 'type here and click send to display a message on Pi 2'. Thanks in advance.

Hi Satya, thanks for the Tutorials, I am making a home automation system, and using a simple led as a test, is it possible, if I press ON button on my phone and when another person open the page on another phone or pc the button press is reflected on both interfaces interactively at the same time

Wow, you use post request. It bad idea, use Sockets, it much faster.
