Thread: Water level sensor

Hi, I am doing water level sensor. I want to display 3 different values in my 7 segment. For example when the water level reaches 10cm which is the alert(A) the 7 segment also need to show 10,when the water level reaches 20cm which is the warning(W) the 7 segment also need to show 20 and when the water level reaches 30cm which is the emergency(E)the 7 segment also need to show 30. But right now with the below code it can only shows the emergency level(E) where the water level reaches 30cm the 7 segment also show 30 but cannot display for other 2 levels. The code uses C progremming. What are the changes need to be made in the code. Please respond to me as soon as possible. Thank You.
