Text Box: For this program to work, the two sensors have to be connected to the same port. The program then accepts input from either sensor, but it just canít tell from which one. (To solve this problem it is not important to know which one of the sensors was pressed).
Sensors can be stacked on the same port, and the program can receive input from either one. However, it canít tell which one has been pressed.
