Logic tester

Lucas and I put this together to test AND, OR and NOT logic gates. With a IC socket one can plug any of these in and select the inputs and see the outputs to test the IC and/ or help understand the logic.

This logic tester should be easy to put together and help understand logic gates.

It also tests AND, OR and NOT gates (okay, the NOT is actually an inverter since it does not make a "decision").

Note each input has a switch with 1 or 0 and when 1 will light a red LED to verify the input. A blue LED will show the output.

For AND and OR gates, we used pins 1 and 2 for inputs and the 3 for output.

Note for the inverter (NOT "gate") we used pins 8 and 9.
