echoSense Circuit Diagram

This is the correct circuit diagram for implementation of this project. We didn't use a breadboard for our final version but the wiring still remains the same.

Code

echoSense

Simply copy paste the contents of the .ino file into the Arduino IDE, and choose your selected board (be sure to comment out the Circuit Playground specific functions). Import the HC-SR04 library, and upload to the board.
