If you're interested in building the complete project, you can refer to the list of supplies required. Throughout this project, you'll primarily work with fundamental logic gates such as XOR, AND, and OR gates, which are essential components in digital circuits. Each full adder has a carrying value and a sum value, with the carry values propagating into the next full adder until the final one, where any remaining carry value becomes the 5th output. In comparison to the 2-bit adder, the 4-bit version requires one half-adder and either three full adders or four full adders. With the 4-bit Adder, you'll be able to perform calculations up to 15+15, resulting in 30 in decimal. Don't worry if you're new to these concepts it's advisable to refresh your knowledge of binary conversions and familiarize yourself with logic gates. To bring this project to life, you'll work with 74xx series IC chips and logic gates. Designing a 4-bit Adder as part of your Engineering Final Project will allow you to create a simple calculator that can add two 4-bit binary numbers. If you have a basic understanding of binary conversions and logic gates, this project is an excellent choice for you.
