How do I troubleshoot my Arduino sensors?

My temperature sensor isn't giving accurate readings. What should I check?

First, ensure that the sensor is properly connected to the Arduino. Check the wiring and connections.

I've checked the connections, and they seem fine. What else could be wrong?

Next, verify that you're using the correct library for your sensor and that it's properly initialized in your code.

I think I might have the wrong library. How can I find the right one?

You can check the manufacturer's documentation for your sensor, which usually lists the compatible libraries.

Thanks! What if the sensor still doesn't work after that?

If it still doesn't work, try testing the sensor with a simple example sketch to isolate the issue.
