An example of an AI chatbot conversation about troubleshooting Arduino serial communication issues.
How do I troubleshoot serial communication issues with my Arduino?
First, ensure that your Arduino is properly connected to your computer and that the correct COM port is selected.
I've checked the COM port, but I'm still not receiving any data.
Make sure that the baud rate in your code matches the baud rate set in your serial monitor.
What if the baud rates match but I still see garbage data?
This could be due to incorrect wiring or a faulty connection. Double-check your connections and try using different cables.
Are there any specific libraries I should use for serial communication?
Yes, the 'SoftwareSerial' library can help if you're using multiple serial devices. Make sure to include it in your sketch.
