Ultrasonic Sensor - Arduino Code Download ((HOT))

In this tutorial we will learn how the HC-SR04 ultrasonic sensor works and how to use it with Arduino. This is the most popular sensor for measuring distance and making obstacle avoiding robots with Arduino.

In this case, we need this set to it HIGH, as the HC-SR04 sensors sets the Echo pin to High after sending the 8 cycle ultrasonic burst from the transmitter. This actually starts the timing and once we receive the reflected sound wave the Echo pin will go to Low which stops the timing. At the end the function will return the length of the pulse in microseconds.

In the previously explained code we manually triggered the sensor and measured the received signal pulse duration. Then according to those results we calculated the distance based on it. Using the NewPing library we can get the distance with just a single line of code.

Dear Dejan, I am building a simple robot with this sensor. The problem is this: I want to avoid a collision at a distance of about 50 cm. How do I implement in code this value in the simple software I made. (the robot is programmed to drive an eight) with simple code as digitalWrite HIGH or LOW on two pins.

The problem might be that you are using Arduino DUE, which has 3.3V pins and the ultrasonic sensors is working with 5V. Try using an resistor at the echo pin, as the 3.3V are fine for the Trig pin, but the Echo pin of the sensor will output 5V to your Arduino DUI which might damage it.

Some manufacturers provide the ultrasonic sensor that has 3 pins. TRIG signal and ECHO signal are in the same pin. In this case, we need to use only one Arduino's pin for both purposes: generating a pulse to the sensor and measuring pulse from the sensor.

The SEN136B5B is an ultrasonic range finder from Seeedstudio. It detects the distance of the closest object in front of the sensor (from 3 cm up to 400 cm). It works by sending out a burst of ultrasound and listening for the echo when it bounces off of an object. It pings the obstacles with ultrasound. The Arduino board sends a short pulse to trigger the detection, then listens for a pulse on the same pin using the pulseIn() function. The duration of this second pulse is equal to the time taken by the ultrasound to travel to the object and back to the sensor. Using the speed of sound, this time can be converted to distance.

It started working properly with te code in the tutorial link you provided.I am still not able to figure out what was wrong with that sensor but I think that it was the high current draw which caused the arduino to reset.It still gives the constant OUT OF RANGE output when the objects in front of it are moving too fast.

hey, i have the same problem, i get is 0CM all the time .

i try many code.

anther thing, before i up-lode the code to the arduino the gnd shortens the circle.

i used in the sensor one year ago and its work , but now no...

Hi all! So i cam across a project online called buddy. it's essentially a handful of servos and an ultrasonic sensor that looks around the room and reacts. so i downloaded the code, and bought the parts, but it's not working as expected. The sensor doesn't actually seem to be reading the distance, and i'm quite the beginner at code and don't really know where i need to be looking.

The second code is measuring the distance perfectly. as i said, it was only to test if i had a defective sensor or not. The first code is one i found online, supposedly a ready to use code to work sith the supplied project.

Hi,

I am currently trying to get my ultrasonic sensor to work using the NewPIng Library.

The sensor is working fine as I can use a simple sketch to get distance measurement. This works ok but for my application I need more accurate and reliable distance measurements.

My problem arises when I use the NewPing library. It is installed correctly.

I am using a sketch which I copied from the DroneBotWorkshop but I get 'Out of Range' whatever I do. I included a couple of extra lines to see if I was getting anything from the sensor which I am not.

Here's the code:

Thanks for the quick reply.

As I said, the sensor works with a simple sketch. The wiring is correct as the sensor works with a simple sketch.

It's when using the NewPing library I don't get any results.

Sorry about the code tags, when I copy and paste the code it comes out all black, I just changed the colour to make it easier to distinguish from my ramblings! How do I post code with all the right colours then?

The HC-SR04 ultrasonic sensor uses sonar to determine the distance to an object. This sensor reads from 2cm to 400cm (0.8inch to 157inch) with an accuracy of 0.3cm (0.1inches), which is good for most hobbyist projects. In addition, this particular module comes with ultrasonic transmitter and receiver modules.

This sensor is very popular among Arduino tinkerers. So, here we provide an example of how to use the HC-SR04 ultrasonic sensor with the Arduino. In this project, the ultrasonic sensor reads and writes the distance to an object in the serial monitor.

Hello all, just got my first arduino, and i have this working. but for my project i need a second ultrasonic sensor. and i have no idea how to do that.

ive added a triggerpin and an echo pin in the code for the second sensor, but how do i define to the code there are 2 sensors? do i need to copy the whole code again for the second sensor? or can the code run for both at the same time?

I am ordered over 100 of these sensors for a class, and well over 75% have this issue, regardless of which code, library, or timing I am using. A previous set of 100+ ordered last year do not have this issue, and the ticking cannot be heard.

Flicking it or resetting the power seems to fix the problem until I max out the range or change distance quickly again.

Did you find a solution or cause to the issue?

Hi,

I am using ultrasonic sensor to classification of milk based on viscosity. So for that i want the code so please help me

condition:

If range is between 0cm to 4cm then display viscosity is high

If range is between 4cm to 7cm then display viscosity is medium

If range is between 7cm to 10cm then display viscosity is low.

Hai sir, I have interfaced ultrasonic sensor with Arduino using serial monitor. Now, I want to interface LCD to monitor the distance values could you please provide the schematic to interface LCD with Arduino.

I have purchased the ultrasonic sensor

uitechies.co.in/BBBcircuits/product.php?product=ultrasonic-range-finder-module-sensor-distance-measuring-transducer

hi, it is really helpful to understand the coupling of the sensor with the Arduino.

thanks in advance.

I need some info. i am intending to connect 5 ultrasonic sensors in my project. Then how should i connect the Trig and Echo pins. either i should mutually join all respective wires of all five sensors and then connect the wires to the arduino digital pins, or i should connect the trig and echo pins of all five sensors to connect in the arduino, separately.

hope you will hear from me soon.

I have had many problems getting the Ultra Sonic sensor to work in combination with servo motors and/or encoder motors. From my experience and from what I have read they all use the same timer and with more than one device the timer(s) get confused which pulse they are timing. Random, jerky and erratic movements result ruining the entire project. Seems like a bad design to me. Is there a solution to this?

The TRIG_PIN is used to send the trigger signal, and the ECHO_PIN is used to receive the echo signal.

The pulseIn() function measures the duration of the pulse from the echo pin, which corresponds to the time taken for the ultrasonic wave to travel to the object and back.

The speed of sound is approximately 343 meters per second (or 34300 cm/s). The formula used in the code calculates the distance based on this speed and the time of flight of the ultrasonic wave.

The calculated distance is then printed to the Serial Monitor.

Hi,I am just starting to explore posibilities to make something work in processing via arduino (sensors). On school exhibition I want to make a picture display that shows one image at the time on the wall (with a projector), depending how close or far person is located from distance sensor.This is a sketch of what I am thinking about:To see if it really works, I explored some tutorials that explains how to connect Arduino input with Processing. Currently, I have these codes in both programs:for Arduino:

The code works when I put my hand in front of the sensor, it moves the servo. When I pull my hand away from the sensor the servo goes back to its neutral position. I need this code to work for two separate servos and two separate sensors. One sensor per servo.

I am tinkering with a simple Arduino sketch that detects distances using an ultrasonic sensor. From what I've understood, the trigger sends a ping. The echo listens for an echo that comes back to calculate the distance. This is measured in microseconds.

I encountered problems trying to get readouts from the ultrasonic sensor in the mBot. After much tinkering and forum reading (with help from a post by @benjamin.m,) I was able to come up with this code that allows you to get sensor readouts using the COM window while connected via USB cable.

Hi, I dont know how old this post is, but I would like to know if you can show this code

in mblock form instead of arduino code, for arduino, Im trying to assemble multible block
