This document describes a water level indicator circuit that uses a 7-segment display to indicate the water level in a tank. It lists the group members and components of the circuit, including resistors, LEDs, batteries, IC chips, a buzzer, and 7-segment display. It provides details on the main circuit and how it functions in empty, partially filled, and completely filled states of the tank, displaying E, P, and C respectively on the 7-segment display. It concludes by thanking the reader.
