How can I control the GPIO via a Web page?

How can I control the GPIO via a Web page?

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.

How do I change my GPIO pin?

How to set an output – full Python code

1. import RPi.GPIO as GPIO # import RPi.GPIO module.
2. GPIO.setmode(GPIO.BCM) # choose BCM or BOARD.
3. GPIO.setup(port_or_pin, GPIO.OUT) # set a port/pin as an output.
4. GPIO.output(port_or_pin, 1) # set port/pin value to 1/GPIO.HIGH/True.

How do I control RPi GPIO pins?

How to Control GPIO Pins on Your Raspberry Pi

Is Flask a framework?

Flask is a micro web framework written in Python. It is classified as a microframework because it does not require particular tools or libraries. However, Flask supports extensions that can add application features as if they were implemented in Flask itself.

How to control GPIO pins in ESP8266 WebSocket server?

The ESP8266 Websocket server will be developed using PlatformIO. To describe how to enable a real-time data transfer from the web page to the ESP8266 Websocket server, we will suppose that we want to create a web page that has a switch to turn on or off a LED controlling the GPIO Pin. The pin status code is sent using the Websocket protocol.

How to control Raspberry Pi GPIO via HTTP web server?

Control Raspberry Pi GPIO using python http.server library The python http.server library creates and listens at the HTTP socket, dispatching the requests to a handler. This allows user to create a simple web server without installing LAMP.

How to create a web server with a Raspberry Pi?

Raspberry Pi Web Server using Flask to Control GPIOs In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs. You can replace those LEDs with any output (like a relay or a transistor). In order to create the web server you will be using a Python microframework called Flask.

How does the ESP8266 connect to the WiFi?

The last part is gluing all the pieces so that the Webserver and the Websocket server starts correctly and the ESP8266 connects to the WiFi: This piece of code is very simple. The ESP8266 provides a web page that is loaded by the browser as it connects to the Web server.
