Logic OR Gate

About: Electrical Engineer, control systems, automation, small electronics, home automation, microcontrollers etc.

The OR gate is a logic Boolean gate that represents addition in basic algebra. If either of the inputs or both inputs to a basic OR gate are forced to logic HIGH (1) the output is forced to logic HIGH (1). If both of the inputs are forced to a logic LOW (0) the output is forced to a logic LOW (0). This closely resembles the addition statement where only Boolean variables are allowed. The symbol and truth table for an OR gate can be seen here.

    Good explanations about the logic gates but why don't you make them all in one instructable.
