This initiative guided two student groups in designing and presenting end-of-term projects focused on digital circuits. Using IC logic gates provided by Stevens, students created simple circuits employing AND, OR, XOR, and NAND gates. They constructed a half adder model to showcase fundamental principles. Students also engaged in testing completed circuits, integrating switches and functioning LEDs for various logic inputs. Presentations included comprehensive coverage of gate types, logic tables, and the basics of Boolean algebra as pioneered by George Boole.

Circuits Advised students with end of term projects and provided guidance for two groups working with digital circuits. • Student designed project (AP physics) • Digital logic and Boolean algebra exercise. • IC logic gates brought from Stevens were used in making simple circuits. • Students demonstrated models with AND, OR, XOR, NAND etc.. gates. • Model half adder constructed by students along with their presentation to demonstrate principles to rest of class.
