<br>
==Introduction==
keyestudio SR01 Ultrasonic Module V2 is a very affordable proximity/distance sensor that has been used mainly for object avoidance in various robotics projects.  It uses upgraded N76E003AT20 solution. <br>
It essentially gives your Arduino eyes/spacial awareness and can prevent your robot from crashing or falling off a table. <br>
It has also been used in turret applications, water level sensing, and even as a parking sensor. <br>
This simple project will use the SR01 ultrasonic module V2 with an Arduino and a processing sketch to provide a neat little interactive display on your computer screen.

==Sample Code==
<pre>
#define echoPin 7 // Echo Pin
#define trigPin 8 // Trigger Pin
#define LEDPin 13 // Onboard LED

int maximumRange = 200; // Maximum range needed
int minimumRange = 0; // Minimum range needed
long duration, distance; // Duration used to calculate distance

void setup() {
 Serial.begin (9600);
 pinMode(trigPin, OUTPUT);
 pinMode(echoPin, INPUT);
 pinMode(LEDPin, OUTPUT); // Use LED indicator (if required)
}

void loop() {
/* The following trigPin/echoPin cycle is used to determine the
 distance of the nearest object by bouncing soundwaves off of it. */ 
 digitalWrite(trigPin, LOW); 
 delayMicroseconds(2); 

 digitalWrite(trigPin, HIGH);
 delayMicroseconds(10); 
 digitalWrite(trigPin, LOW);

 duration = pulseIn(echoPin, HIGH);
 
 //Calculate the distance (in cm) based on the speed of sound.
 distance = duration/58.2;
 
 if (distance >= maximumRange || distance <= minimumRange){
 /* Send a negative number to computer and Turn LED ON 
 to indicate "out of range" */
 Serial.println("-1");
 digitalWrite(LEDPin, HIGH); 
 }
 else {
 /* Send the distance to the computer using Serial protocol, and
 turn LED OFF to indicate successful reading. */
 Serial.println(distance);
 digitalWrite(LEDPin, LOW); 
 }
 
 //Delay 50ms before next reading.
 delay(50);
}

== What Should You See ==

After upload the code to the board, open the serial monitor of Arduino IDE, and set the baud rate to 9600. <br>
Move your hand or a large, flat object closer and farther away from the distance sensor. You can see the measured distance value pop up on the monitor.
