Sonar Mouse click

So here is a fun quick project that helps you play Minecraft without clicking... just put your hand right above the sonar detector and that does the mouse click for you. This project is part of my augmented gameplay projects to increase functionality of the game or playability.

For the sonar detector I used the HC-SR04 that was part of the Elegoo 37 sensors kit. So please use and download the sonar the library at

https://www.elegoo.com/pages/arduino-kits-support-files

Then add the "new ping" library by adding the HC-SR04 . zip library to your Arduino sketch.

Also please use the Elegoo tutorials at https://people.engr.tamu.edu/slupoli/notes/Robotics/Arduinos/Elegoo37SensorKit/37%20SENSOR%20KIT%20TUTORIAL%20FOR%20UNO%20AND%20MEGA.pdf

You do not need to buy the 37 sensors kit for this project just buy the HC-SR04 and download the free libraries and pdf reference.
