10, Test results

Arduino UNO test results:

In the case of the flame sensor module being powered on, adjust the module potentiometer with a small screwdriver, when the flame is detected, the sensor signal indicates the blue light is on, and when there is no flame detected, the module signal indicates the blue light is off.
