This document summarizes a student project on simulating and building a half adder circuit on a general purpose PCB board. The project aims to understand how a half adder circuit works, demonstrate skills in designing practical circuits, and increase technical knowledge. A half adder adds two binary digits and outputs the sum and carry. The student team simulated and built the half adder circuit using components like an XOR gate, AND gate, LED, wires and a PCB board. The circuit demonstrates applications of half adders in computer arithmetic logic units and building full adders. Completing the project helped develop skills like problem solving, critical thinking and teamwork.

4. INTRODUCTION
A half adder is a type of adder, an electronic
circuit that performs the addition of numbers.
The half adder is able to add two single binary
digits and provide the output plus a carry value.
It has two inputs, called A and B, and two
outputs S (sum) and C (carry).

 An adder is a digital circuit that performs
addition of numbers. The half adder adds two
binary digits called as augend and addend and
produces two outputs as sum and carry; XOR is
applied to both inputs to produce sum and AND
gate is applied to both inputs to produce carry.

 1) The ALU (arithmetic logic circuitry) of a
computer uses half adder to compute the binary
addition operation on two bits.
 2) Half adder is used to make full adder as a full
adder requires 3 inputs, the third input being an
input carry i.e. we will be able to cascade the carry
bit from one adder to the other.

11. SKILL DEVELOPED
 Complex problem-solving skills and a methodical mind.
 Critical thinking.
 Strong interest in technology.
 Aptitude for maths.
 Communications skills.
 Time management and an ability to prioritise and plan
work effectively.
