A question if i want to connect a buzzer where would i go

[@Flaretech.in_]

you can connect a buzzer instead of led ,the wiring is same

[@currentissues2447]

you r doing great job bro

[@purple_pink_skies]

Very useful information, thank you. When I try this myself for my school project, the LED turns ON from the time the circuit is powered on. It does not wait till the sensor receives an input. What could be wrong? Please help!

[@kmanrajan]

Thanks

[@pratiksbuddhe5311]

sorry..i got it.
thank you.

[@berna2547]

Thank you..

[@kuldeeppanchalblog]

thank you bro
It's very helpful for beginners
But, please upload more videos for arduino tutorial

[@MechStuff]

yes... sure... I had some technical problems... I'm gonna post videos soon.. Subscribe so that you'd come to know when I post them & stay tuned :)

[@elmacho5153]

Hey, I just constructed the ultrasonic sensor and uploaded the code, but I have a problem. The pager motor I used for vibration keeps on vibrating, and the sensor doesn't detect any objects or distance. What should I do?

[@goutamrajput5287]

Thanks! 😊

[@Jas_01101]

Can you show the values that you are printing on the serial monitor??

does the code also contains sms text message phone feature?

[@despaap]

Thank you so much bro!

[@deja7f384]

Thx, you helped me!

[@darimages2803]

Great tutorial. I can't find the HC-SR04 part for sale on the Arduino website, is this part still available?

[@arshkenia9698]

You can buy it in a very reasonable price from this link : botuniverse.in/index.php/product/hc-sr04-ultrasonic-sensor/

[@abdalqadermhemed4075]

This code for who found that the led stay on , this because you didn't clear the trigger , check the following code
int trigger=9;
int echo =10;
void setup(){
Serial.begin(9600);
pinMode(trigger ,OUTPUT);
pinMode(echo,INPUT);
pinMode(7,OUTPUT);
}
void loop(){
long duration,distance;
digitalWrite(trigger ,LOW); //clears the trigger , else its not gonna measure more than one value
delay(0.2);
digitalWrite(trigger,HIGH);
delay(0.1);
digitalWrite(echo,LOW);
duration=pulseIn(echo,HIGH);
distance =(duration*0.034)/2;
Serial.print(distance);
Serial.println("CM");
if(distance 10){
digitalWrite(7,LOW);
}
delay(1);
}

[@androidemulation5952]

I'm using an arduino provided by elegoo, i was working on a home security System as a school project. And i did somthing similar to what you did and everything works fine when i connect the ultrasonic sensor alone. However, when i add other sensors and motors a started getting wrong reading which turn on the alarm for no reason. What do you think is the problem?

[@androidemulation5952]

For those who has similar problem s, try using Relays with external output source and take the average of the sensor readings. The more readings you take the better but with more delay.
That solved the problem for me. Hope it works for you

[@adityaingale1233]

bhai kya aap aisa border security system sensor bana sakate ho ki border ko kisi bhi kone ko touch kare udhar hi gun fire kare please mi replay

[@avishekkumarbanka401]

can i modify this circuit for gps tracking and water and light senser blind stick???????

[@happyboyshappy33]

bro can you upload a video about how to connect ultra sonic sensor with arduino and motor without any motor driver and diode and transistor

[@haricharan1073]

Brother can you prepare obstacle avoiding robot with help motor shield

[@lohithchowdary239]

Hi bro I want to do this project. Can u helpe

[@neerigattisomasekhar4910]

nice explanation .can u upload how to dump programme into the aurdino so that i can complete my project

[@1994grigala]

thank

[@abhishekkoppu]

you

[@esa2236]

Also for line 20, why do you have a * operator instead of a =?

[@amrothman4064]

can you give me the link of the aduino

[@rammalvi2590]

Sir plz programming ka video banayeg

[@PrashantKumarPrasad]

Plz , make a video on 2.4" tft Screen

[@eruditeoverseasconsultants5446]

please paste the code in the description

[@TechsScience]

Better to use different color wires to avoid confusions
Overall i liked this video

[@levida4032]

can you pls tell which software to use for coding and how to upload the program to the board.

[@shiladityagida8988]

Can we increase the distance of 10 centimetre ?

[@pradeepchilamakuru1536]

sir if you want to add buzzer whats the code
plz tell me sir

[@jerseyboys6201]

What should i do if i want to set the distance on 1 meter or 1 centimeter ?

[@srimathivelusamy714]

Problem occurs when coding uploading to board...what can i do?

[@tanishqsachinmandolkar9529]

best

[@farukozgur6514]

I'm trying to transfer the distance I get from hc-sr04 sensors to thingspeak using Nodemcu. Only when measuring distance the sensors work very well but when I write the code to transfer the data to thingspeak or firebase the sensors work very slowly. What could be the reason for this? how can i fix it

[@brandonb2201]

Nice tutorial! Instead of using a LED you can use the builtin LED on the arduino. Instead of int led just use the function LED_BUILTIN where you digital write.

[@sddinesh4974]

Bro pls give best buy link for aurdino

[@koushikkota6293]

Bro,what is 29.1 value stands for in distance formula

[@dmitryoulianov9214]

It's the inverse of the speed of light in centimeters per microsecond units (see full explanation below) - i.e. 29.1 ~ 1 / 0.0343
Let's use the following abbreviations and operations:
S - speed
D - distance
t - time (or "duration" in the video)
m - meters
cm - centimeters
s - second
μs - microsecond
* - multiplication operation
/ - division operation
We know that the speed of sound is 343 m/s or 0.0343 cm/μs.
Distance equation is: D = S*t
Function "pulseIn()" returns the full time traveled by the sound in microseconds.
Since we know the speed (the speed of sound) and time traveled ("duration" value returned by the "pulseIn()" function), we get D = 0.0343 * duration.
We actually need only half of the distance because the "pulseIn()" function returns the time traveled to the object and back, but we need only the distance to the object.
Hence, we divide the full distance traveled by the sound by two, and our distance to the object is equal to: 0.0343 * duration / 2.
We can rewrite this as: (duration / 2) * 0.0343 or (duration / 2) / (1 / 0.0343)
Since (1 / 0.0343) is equal to approximately 29.1, we get the distance to the object (in centimeters) equal to: (duration / 2) / 29.1

Clear label sansor u can say

[@leanderpereira5257]

Will the led not burn?

[@vishnupatil5725]

how will you put code in ardino
