How do I troubleshoot sensor issues with my Arduino?

First, can you specify which sensor you're having issues with? It will help narrow down the troubleshooting steps.

I'm having problems with a temperature sensor. It seems to give inconsistent readings.

Inconsistent readings can be caused by several factors. Have you checked the wiring and connections to ensure they're secure?

Yes, the connections seem fine. What else could be the problem?

Next, check the code you're using. Make sure you're reading the sensor data correctly and that the sensor is calibrated.

I think the code is fine. Could it be a hardware issue?

It's possible. Try testing the sensor with a different Arduino board or using a multimeter to check its output.
