Thank you so muchh bhai

[@JakobDam]

Short, effective and straight to the point - thanks for the tutorial. Also, well commented code.

[@farrelmachmoed3045]

i cannot get the code running because Distance was not declared onscope

[@pickygaming3136]

so when i plugged it in my computer disabled usb ports because it was using to much power and i unplugged everything and it still wouldnt work

[@agled]

I was thinking about to download a library just to do this, but you just show me how easy is to make. Tks

[@SKY53.]

Code:
const int TriggerPin = 8; //Trig Pin
const int EchoPin = 9; //Echo Pin
long Duration = 0;
void setup() {
// Put setup code here, to run once:
pinMode(TriggerPin, OUTPUT); //Trigger is an output pin
pinMode(EchoPin, INPUT); //ECHO is an input pin
Serial.begin(9600);
}
void loop() {
// main code:
digitalWrite(TriggerPin, LOW);
delayMicroseconds(2);
digitalWrite(TriggerPin, HIGH); //Trigger Pin to HIGH
delayMicroseconds(10); //10us high
digitalWrite(TriggerPin, LOW); //Trigger Pin to HIGH
Duration = pulseIn(EchoPin, HIGH); //Wait for the Echo Pin to get high
//Return the duration in milliseconds
long Distance_cm = Distance(Duration); //Use function to calculate the distance
Serial.print("Distance = "); //output to serial
Serial.print(Distance_cm);
Serial.println(" cm");
delay(1000); //Wait to do the next mesurement
}
long Distance(long time)
{
long DistanceCalc;
DistanceCalc = ((time * 0.034) / 2); //Actual calcutatio in cm
//Distance = time / 74 / 2 //Actual calcutatio in inces
return DistanceCalc; //Return calculated value
}

I used the same code but it didn't work. The program is giving errors in the code.

can we attach a buzzer with this ??

Can u please interface two ultrasonic sensors..one will send ping and other will recieve

[@FlorianDREVET]

Why is your goal with trying to use two ultrasonic sensors ? It will works with only one.

[@jhojanbohorquez8402]

i cant access to sketch :(

how to i gave this code

[@sudhanshudeshpande6187]

It is only showing output as "Distance=0 cm".. That`s it value is not changing.. Plz help me

I have the same problem. Did you ever get pass it?

Same here

[@vinicius71999]

​@@marcelodive Conseguiu resolver?

[@marcelodive]

@@vinicius71999 , acho que era um problema utilizando "delay()" em outras partes do código, mas confesso que não lembro 100% como consegui resolver. Quer que eu dê uma olhada no meu código mais antigo?
