4-Bit Adder built from logic gates

The goal of this project was to build a "4-Bit Adder" starting from XOR, AND, & OR logic gates. I used QUAD chips that contained 4 of each type of gate. The circuit takes two 4-bit binary numbers and adds them together to output a 4-bit binary sum & a single carry bit. Along the way of building the circuit, I ran into challenges with resistors at the inputs and at the LEDs. Also, it is likely that there are differences in internal resistances of different chips in the market. The challenges were overcome and the project completed successfully. The 4-bit Adder is a fundamental component of a digital computer's "ALU" or "Arithmetic Logic Unit".
