Under the guidance of three faculty members, the document provides instructions for building a NAND gate circuit on a breadboard using common electronic components like resistors, LEDs, transistors, a power supply source, and switches. The circuit allows students to experiment with and understand the functionality of a basic NAND logic gate.
