ARDUBLOCK Project 11:Ultrasonic Distance Measurement

Introduction:
In this project, we use graphical programming to measure the distance between ultrasonic module and front obstacle and display it on serial monitor.
Materials Required:

• 1. KEYESTUDIO UNO Control Board *1
• 2. V5 Sensor Shield*1
• 3. Ultrasonic Module*1
• 4. Female to Female Dupont Line*4

Connection Diagram:
Let’s start experiment, and connect ultrasonic waves to ARDUINO referring to the following figure.

After wiring, we can start programming.

Click “download to Arduino” to see the following codes in ARDUINO programming interface:
Sample Code:

*****************************************************************************
int _ABVAR_1_t1 = 0 ;
int ardublockUltrasonicSensorCodeAutoGeneratedReturnCM(int trigPin, int echoPin)
{
  long duration;
  pinMode(trigPin, OUTPUT);
  pinMode(echoPin, INPUT);
  digitalWrite(trigPin, LOW);
  delayMicroseconds(2);
  digitalWrite(trigPin, HIGH);
  delayMicroseconds(20);
  digitalWrite(trigPin, LOW);
  duration = pulseIn(echoPin, HIGH);
  duration = duration / 59;
  if ((duration < 2) || (duration > 300)) return false;
  return duration;
}

void setup()
{
  digitalWrite( 4 , LOW );

  Serial.begin(9600);
}

void loop()
{
  _ABVAR_1_t1 = 	ardublockUltrasonicSensorCodeAutoGeneratedReturnCM( 4 , 5 ) ;
  Serial.print("diatance:");
  Serial.print(_ABVAR_1_t1);
  Serial.println();
  delay( 200 );
}
*******************************************************************************

Result:
We can see the distance value measured by ultrasonic in the serial monitor of ARDUINO after downloading the program.
