Figure 1 is an annotated screenshot of a Serial Monitor window Writes binary data to the serial port. This example will show how to set up the Arduino, initialize the serial communication, and print a message to the Serial Monitor. println() sends data to the serial port with an added newline character, simplifying debugging and communication in Arduino projects. Therefore, the Serial Monitor only works when the Arduino board is tethered to the host computer that is running the Arduino IDE. In Arduino, when I scan I2C lines it is scanned only on 0 and 1, as default. Some devices work using bytes to set configurations, commonly use packets of data and you need to use write function to communicate with them. I wrote this simple code and still have not been able to get anything to show up on the serial monitor. h and it works well with an arduino uno.
