Arduino Adder

This is a project I created for my intro to microcontrollers class! It took me some serious troubleshooting to get this circuit to run clean. It works off of USB Power but needed to adjust the voltages that each analog input sees when a switch is closed or open for it to work properly. I also added two 0.1 microFarad capacitors in parallel to the voltage supply and ground to clean up the signal coming into the Analog to Digital Conversion pins. This build was made with an Arduino UNO R3 microcontroller and parts from Sunfounder and ELEGOO starter kits. I hope to link the schematic and code shortly from my website :)
