Hello Everyone! Welcome to our first instructable! Today we are going to show you how to build a 4 bit binary adder with simple logic gates. This is a part of a series we are doing to make a functional calculator so stay tuned for more!!

Step 1: Watch the Video!

You first need to know the basics. I have explained them in detail in this video.

Step 2: Get Your Components!

You will need these for your build:

2 74ls86 ICs: https://www.amazon.com/QUAD-2-INPUT-EXCLUSIVE-GATE-DIP-14/dp/B00GAGBX36/ref=sr_1_3?ie=UTF8&qid=1529913747&sr=8-3&keywords=74ls86

2 74ls08 ICs: https://www.amazon.com/TEXAS-INSTRUMENTS-SN74LS08N-DIP-14-pieces/dp/B00LQQPWAA/ref=sr_1_4?s=industrial&ie=UTF8&qid=1529913833&sr=1-4&keywords=74ls08

2 74ls32 ICs: https://www.amazon.com/QUAD-2-INPUT-POSITIVE-GATE-DIP-14/dp/B00GAGBURA/ref=sr_1_4?s=industrial&ie=UTF8&qid=1529913885&sr=1-4&keywords=74ls32

5 LEDs

A Mobile Adapter(5v)

Jumper Wires: https://www.amazon.com/Solderless-Flexible-Breadboard-Jumper-100pcs/dp/B005TZJ0AM/ref=sr_1_3?s=industrial&ie=UTF8&qid=1529913965&sr=1-3&keywords=jumper+wires

Breadboard: https://www.amazon.com/eBoot-Experiment-Solderless-Breadboard-400-Points/dp/B01MG5IPUX/ref=sr_1_12?s=industrial&ie=UTF8&qid=1529914016&sr=1-12&keywords=breadboard

2 Dipswitches: https://www.amazon.com/Uxcell-Positions-2-54-Pitch-Switch/dp/B011BL6K50/ref=sr_1_4?s=industrial&ie=UTF8&qid=1529914137&sr=1-4&keywords=4+way+dip+switches

Some 370 ohm resistors: https://www.amazon.com/Projects-250EP514330R-330-Resistors-Pack/dp/B01LYKLJRD/ref=sr_1_2_sspa?ie=UTF8&qid=1529914198&sr=8-2-spons&keywords=330+ohm+resistor&psc=1

Step 3: Assemble and Have Fun!

Assemble as told in the video above. Now by manually checking we can assure our self that we have successfully built a full adder for 4 bits. I hope you enjoyed this project!

Be sure to check our youtube channel for more! We will see you later with something new and amazing!
