Scaling image using ultrasonic sensor and Processing

Introduction

As our WhatsApp group member have requested we are going to scale the size of an image using the distance value acquired  from a ultrasonic sensor HC SR04. shower the distance smaller the image size and farther the distance bigger the size of image.

Construction

As you can see in the circuit connect the trigger pin of HC-SR04 sensor to digital pin 12 , echo pin to digital pin 11 and VCC of sensor to 5v of arduino and GND to GND of arduino.

Arduino UNO	HC-SR04
Digital 12	Trigger
Digital 11	Echo
5V	VCC
GND	GND

The Arduino code is library example with a small change, We will be needing "new ping" library to compile our Arduino code. You can download it here
