DAU Firmware and upload tool for the Arduino Opta.
Modbus TCP controller running on Arduino Opta
This project uses an Arduino Opta (using Arduino PLC IDE) in combination with a Shelly Pro Dimmer 2PM to replace an existing lighting control module that uses a 0–10V signal for dimming and control.
Add a description, image, and links to the arduino-opta topic page so that developers can more easily learn about it.
