Ultrasonic Sensor (Large)

Liam Brady

Ultrasonic sensors are distance sensors that use sound waves to detect how far away an object is. They send out high frequency bursts of sound and listen for its echo. They then determine how far away the object is based on how long it takes for the sound to return to the sensor. This variety requires an Arduino library to operate.

 

NewPing Library

#include <NewPing.h>

NewPing mysensor(5, 6, 200);

void setup() {
  Serial.begin(9600);
}

void loop() {
  int pingTime = mysensor.ping();

  int distance = mysensor.ping_in();

  int distance_cm = mysensor.ping_cm();

  Serial.println(distance);
}

Blink Code 

Testing your arduino connection

Before you start using your tiny new computer (aka Arduino) you are going to run a test. Using the blink code, you will be able to see a simple physical output where a built in LED blinks from the board.


Before you begin, you will need the Arduino Software downloaded. Refer to the link below this post for instructions.
