How to control Raspberry Pi via HTTP web server?

Run the python script with the following command: Launch your browser and point the URL to the IP address and port of your Raspberry Pi, and you should see the web page, click on On/Off buttons to control the LED that connected to your Raspberry Pi. If you don’t know your Raspberry Pi’s IP address, run the following command to find out:

You bought your Raspberry Pi, and managed to create a python script to turn on/off an LED via GPIO. Then you are wonder “How can I control the GPIO via a web page”?

JavaScript is most commonly used in web browsers, to make websites dynamic and easier to use. You can also run JavaScript on the command line, just like Python. The application that handles this is called Node.js. Unlike Python, Node.js is not installed in Raspbian by default and there are different versions for different hardware.

For a simple test, you can clone the GitHub package: Before we start the server, the other packages have to be installed: The Raspberry Pi Node.JS server can then be started. Since we use the GPIOs we have to start it with sudo.

This is the best place to start if you would like to make VoIP telephone calls from Raspberry Pi as it explains what hardware and software requirements are needed, and how to use them to be able to initiate VoIP calls. VoIP is the acronym for Voice over Internet Protocol.

Thankfully this can be easily accomplished with a tool called ddclient which we can install on our RPi (or any other Debian-based OS such as Ubuntu). ddclient is a service that runs on our server and retrieves our public (WAN) IP address.

PiTunnel is a service for remotely accessing your Raspberry Pi, and the projects that you build on it. A Device Monitor and Remote Terminal is included, and you can also create your own Custom Tunnels to access services running on your Raspberry Pi.
