Summary of the Circuit

This circuit is designed to interface an Arduino UNO microcontroller with two inductive sensors, a two-channel relay module, and two pilot lamps. The inductive sensors are powered by a 12V 200Ah battery, which also provides power to the relay module through the Arduino UNO. The Arduino UNO controls the relay module, which in turn controls the activation of the pilot lamps. The inductive sensors are connected to the digital input pins of the Arduino UNO to provide input signals based on their sensing.
