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?
Hi Chuck, thanks for reading. And no your mom didn’t me up tot his ;)
I remember your comment from the previous blog post – so yeah, let us know when you build it!
