The purpose of this project is to create a pocket-sized tool for measuring distance from objects. We are going to need an ultrasonic ranging module to get the distance between our tool and the target-object.
Pushing a button connected to the ProTrinket will trigger the sensor and then the distance from the object will be displayed on the LCD screen.
We would also like to create a 3D-printed case for our tool and make it look cool!!!
