Transistor or gate
Electronic

Of course you know an OR gate is a logic circuit that has two or more input terminals and produces a high output when one or more input signals are high.

In this project, we're going to make a transistor OR circuit and see how it works. Note that the input signals are 1 when keys are pressed and at 0 if released. The output signal is 1 when the LED lights up, and 0 when the LED goes out.

Wire the project, turn power ON, and get to the experiment. We believe no more explanation is necessary for you by now!
