Here is an example of how an OR Gate works in real life ...

Or Gate


OR Gates are used for digital door bell systems.

Doorbell


Information

An OR Gate has two inputs - Input A and Input B.

The output (Output Y) will be positive (TRUE) if at least one input is TRUE.

We can write the simple equation for this Logic Gate ... Y = A OR  


Information

The output is TRUE if either or both of the inputs are TRUE.

If both inputs are FALSE  then the output is FALSE.

It doesn’t matter if one input is FALSE, if the other input is TRUE the output will be TRUE - because this gate only needs one of the inputs to be TRUE.
