Arduino project 1

This is my first arduino project.

What does it do?

• Communicates with Processing to activate the distance sensor
• displays the distance in inches on a liquid display screen
• allows the user to toggle the display if the Processing window is clicked

Components used

• Arduino Uno Rev 3
• 16x2 LCD Display
• HY-SRF04 Precision Ultrasonic Sensor (HC-SR04 is just as good)

Schematic
