Raspberry Pi Web GPIO Controller

A complete web-based remote GPIO controller for Raspberry Pi with real-time monitoring, PWM control, and a modern interface.

One-Step Installation

Run the following command in your Raspberry Pi terminal

curl -sL https://raw.githubusercontent.com/SiddhantSilwal/RaspberryPi-GPIO-Web-Controller/refs/heads/main/webinstaller.sh | bash

Alternative Installation Methods

For custom installation to review and change python scripts as per your setup, clone and install the git repo as follows

git clone https://github.com/SiddhantSilwal/RaspberryPi-GPIO-Web-Controller.git
cd RaspberryPi-GPIO-Web-Controller/
chmod +x ./install.sh
./install.sh

Requirements

• Python 3.7 or higher
• Curl
• Packages listed in requirements.txt

Running the Application

Autostart:

For default installation the script will autostart on boot

Manual Start:

If autostart is disabled at installation type the following command to start the server

$ webgpio

Access the Interface:

1. Open a web browser
2. Navigate to http://localhost:5000 (local) or http://[PI_IP_ADDRESS]:5000 (network)
