A simple yet effective controller for EBMPapst EC fans, implemented using a Controllino and equipped with an integrated web server. This allows for remote control and monitoring of fan speeds via a user-friendly web interface. The controller is suitable for applications requiring reliable and precise fan speed control.

• Web-Server Integration: Built-in web server for easy access and control over the network.
• MQTT-Client Integration: Built-in MQTT client for easy integration
• PWM Control: Adjust the fan speed using Pulse Width Modulation (PWM) for precise control.
• User-Friendly Interface: A clean and simple web interface, including a dark mode toggle for user comfort.
• Real-time Feedback: Serial output for monitoring current fan speed and system status.

• Controllino (or compatible Arduino-based controller)
• EBMPapst EC Fan or any Fan that has a 0-100% duty cycle PWM input
• Ethernet connection

• SPI Library
• Ethernet Library
• Controllino Library

1. Set up the hardware: Connect the EBMPapst EC fan to the Controllino according to the fan's specifications.
2. Configure Network Settings: Modify the mac and ip variables in the code to suit your network configuration.
3. Upload the Code: Use the Arduino IDE to upload the provided code to the Controllino.
4. Access the Web Interface: Once the Controllino is online, access the web interface using the IP address shown in the serial monitor.

• Adjust Fan Speed: Use the web interface to set the desired PWM value (0-100%) for the fan.
• Quick Set Options: Choose from predefined PWM values for quick adjustments.
• Dark Mode: Toggle between light and dark themes for the web interface.
