Use OR Logic to Build a Game Show Circuit

Weekend Projects maker Max built experiment #21 from Charles Platt’s book Make: Electronics (a great primer for anyone looking to learn electronics or brush up on theories and essentials). This experiment formed the basis for the Game Show Buttons project from earlier this year, and Max does a wonderful job on his Google+ post of giving a simple explanation of this fairly complex circuit and highlighting the various components.

This circuit is built using an OR logic gate, which as the name implies is true (on) if either input A or input B is true. The OR is one of seven common types of logic gates, the others being AND, NAND, NOR, XOR, XNOR, and NOT (or as most call it, an Inverter). If you build Game Show Buttons or any other Weekend Projects, be sure to send us an email with pictures and a story about your build.

    Thanks for the reminder! My mom is a school teacher and she’s been asking for a game buzzer set up for her class room. Looks like this is just the hint I need. Did my mom put you up to this?

      I remember your comment from the previous blog post – so yeah, let us know when you build it!

    Any chance of updating the links for the components. Most of them are unavailable now
