Write a program in Proteus using ATMEGA8 microcontroller that Design an embedded system that controls the water level in the tank using water level sensor. This tank has four level of water. Each level has a height of 0.5m of water. When the tank's water level drops below 0.5m, the pump motor automatically turns on, and Also When the water reaches the highest height in the tank(2.0m), the motor automatically turns off. Also, this system provides water level indication on an LCD.
