Ultrasonic ranger library used for Seeed graphical programming project

Grove_Ultrasonic_Ranger

This Grove - ultrasonic sensor is a non-contact distance measurement module which works at 42KHz, suitable for projects that require middle distance measurement.

Note:

This library is used for Seeed graphical programming Project only.

Library Name：Grove_Ultrasonic_Ranger

API

/* 
 * Function Name: UltrasonicRangerRead 
 * Input: PinName, pin to connect 
 * Return: distance in cm   
 */ 
int UltrasonicRangerRead(int PinName); 

Test Case

Get data from then sensor per 100ms, and print to Serial monitor.   
// test for seeed graphical programming project 
// loovee @ 2015-8-4 
 
#include "Ultrasonic.h" 
 
Ultrasonic ultrasonic; 
const int pin = 2;          // ultrasonic connect to D2 
 
void setup() 
{ 
    Serial.begin(115200); 
    Serial.println("test for Seeed Graphical programming project"); 
    Serial.println("Ultrasonic"); 
} 
 
void loop() 
{ 
    int dist_cm = ultrasonic.UltrasonicRangerRead(pin);         // read data from ultrasonic ranger 
    Serial.println(dist_cm);                                    // display it 
    delay(100); 
}
