Welcome 2nd grade Market Day participants!

Educational demonstration of Boolean AND and OR functions. Requires 5VDC power supply. Uses a single 74LS01 Quad NAND gate IC with open collector outputs to implement both Boolean functions with a single integrated circuit. Power supply pads (+ and -) spaced to fit breadboard power supply rails. However you can elect to use the power supply pads and power it in any manner you choose (short-circuit protection or fuse required).
