Set your Modbus slave (e.g., temperature sensor, PLC) to: Baud Rate: 9600 (match withSerialPort.begin()). Slave Address: 1 (match withnode.begin(1, ...)). Register Address: 0x0000 (adjust in code if needed). Test with aModbus simulator(e.g.,QModMaster) if you don’t have ha...
capabilities. Since you can use an Arduino to read just about any kind of sensor data, the obvious thing to do is use it to detect changes in the environment, light temperature, light levels, and soil moisture. You can even detect sound levels and do motion detection, as well. You can...
