Introduction
This tutorial will provide a step-by-step guide to measuring distance using an Ultrasonic distance module and an Arduino Nano. The tutorial will cover the mathematics behind the process, as well as the code required to make it work.
Arduino Tutorial #5 – Measuring Distance Using an Ultrasonic Distance Module and an Arduino Nano
The fifth Arduino tutorial focuses on using an ultrasonic distance module and an Arduino Nano to measure distance. This tutorial is based on the principle of echolocation, which is the same method used by bats to navigate their environment. By sending out a pulse of sound and measuring the time it takes for the pulse to return, the distance to an object can be calculated.
Setting Up the Ultrasonic Distance Module
The ultrasonic distance module has four pins: VCC, Trigger, Echo, and Ground. VCC is connected to the 5V pin on the Arduino Nano, Ground is connected to the Ground pin, Trigger is connected to pin 8, and Echo is connected to pin 9.
Writing the Code
The code begins by defining the Trigger and Echo pins as variables. The Serial Port is then initialized so that the output can be monitored. The Trigger pin is set as an output pin, as this is the pin that will be sending out the pulse. The Echo pin is set as an input pin, as this is the pin that will be receiving the pulse.
Next, a pulse is sent out by setting the Trigger pin to high for two microseconds and then setting it back to low. The time it takes for the pulse to return is measured by creating a variable called duration. This duration is then used to calculate the distance to the object. The distance is printed to the Serial Port and can be viewed in the Arduino IDE.
So what we do is we call this before we send the pulse out and then we wait for the echo pin to go high and then we call it again and then we subtract the two and that will give us the time of flight.
Ultrasonic Distance Module
An ultrasonic distance module is a device used to measure the distance between two objects. It works by emitting sound waves that are reflected off of the object and then detected by the module. The time it takes for the sound wave to travel from the module to the object and back is used to calculate the distance. This type of device is often used in robotics and automation applications.
Arduino Nano
The Arduino Nano is a small, complete, and breadboard-friendly board based on the ATmega328. It has more or less the same functionality of the Arduino Duemilanove, but in a different package. It lacks only a DC power jack, and works with a Mini-B USB cable instead of a standard one.
Arduino Tutorial #5 – Measuring Distance Using an Ultrasonic Distance Module and an Arduino Nano
In this tutorial, we will be using an ultrasonic distance module and an Arduino Nano to measure the distance between two objects. The ultrasonic distance module works by emitting sound waves that are reflected off of the object and then detected by the module. The time it takes for the sound wave to travel from the module to the object and back is used to calculate the distance.
Connecting the Ultrasonic Distance Module to the Arduino Nano
The ultrasonic distance module has two pins, one for sending a signal (the trigger pin) and one for receiving a signal (the echo pin). The trigger pin is connected to digital pin 8 on the Arduino Nano, and the echo pin is connected to digital pin 9.
Writing the Code
The code for this tutorial is written in the Arduino IDE. The code begins by declaring the pins for the trigger and echo pins. Then, a 10 microsecond high pulse is sent out on the trigger pin. This is followed by a delay of 10 microseconds. The code then listens for the echo pin to go high and then calls the pulseIn() function. The pulseIn() function measures the length of time the echo pin is held high and this is used to calculate the distance between the two objects. Finally, the distance is printed to the serial monitor.
Testing the Code
Once the code is written, it can be uploaded to the Arduino Nano. The distance between the two objects can then be measured by placing an object in front of the ultrasonic distance module and observing the serial monitor. The distance should be printed in centimeters.
Ultrasonic Distance Module
An ultrasonic distance module is a device used to measure the distance between two objects. It works by emitting sound waves at a specific frequency and measuring the time it takes for the sound waves to travel back and forth between the two objects. The device then calculates the distance based on the time it took for the sound waves to travel. Ultrasonic distance modules are commonly used in robotics, navigation, and other applications where precise distance measurements are required.
Arduino Nano
The Arduino Nano is a small, powerful microcontroller board that is used to create interactive electronic projects. It is based on the ATmega328P microcontroller and can be programmed using the Arduino IDE. The Nano is capable of executing complex tasks and can be used to control motors, read sensors, and communicate with other devices.
Arduino Tutorial #5 – Measuring Distance Using an Ultrasonic Distance Module and an Arduino Nano
This tutorial will show you how to measure distance using an ultrasonic distance module and an Arduino Nano. The ultrasonic distance module works by emitting sound waves at a specific frequency and measuring the time it takes for the sound waves to travel back and forth between two objects. The Arduino Nano will be used to control the ultrasonic distance module and calculate the distance between the two objects.
Step 1: Connect the Ultrasonic Distance Module to the Arduino Nano
The first step is to connect the ultrasonic distance module to the Arduino Nano. The ultrasonic distance module has four pins: VCC, GND, Echo, and Trigger. Connect the VCC pin to the 5V pin on the Arduino Nano, the GND pin to the GND pin on the Arduino Nano, the Echo pin to pin 8 on the Arduino Nano, and the Trigger pin to pin 9 on the Arduino Nano.
Step 2: Upload the Code to the Arduino Nano
The next step is to upload the code to the Arduino Nano. The code will read the data from the ultrasonic distance module and calculate the distance between the two objects. To upload the code, open the Arduino IDE and select the correct board and port. Then, copy and paste the code into the IDE and click the upload button.
Step 3: Test the Ultrasonic Distance Module
Once the code has been uploaded, it is time to test the ultrasonic distance module. Open the serial monitor and place your hand in front of the ultrasonic distance module. You should see the distance between your hand and the module changing as you move your hand closer or further away.
Print distance, z. Print distance, so thats in centimeters.
Speed of Sound
The speed of sound is an important factor when measuring distance. The speed of sound is 343 m/s, and this is the standard speed of sound at sea level, with standard atmospheric pressure and temperature. In order to measure distance in centimeters, we must convert this to cm/s. To do this, we multiply 343 by 100, and then divide by 1 million, giving us 0.034 cm/s.
Arduino Code
In order to measure distance using the Ultrasonic distance module and the Arduino Nano, we must write code to calculate the distance. The code must take into account the speed of sound, and use it to calculate the distance. The code must also print the distance to the serial monitor.
The code is as follows:
Float distance = time * 0.034;
Serial.print(distance);
Serial.print(” cm”);
The first line of code calculates the distance by multiplying the time in s by 0.034, which is the speed of sound in cm/s. The second line prints the distance to the serial monitor, in centimeters.
What is an Ultrasonic Distance Module?
An ultrasonic distance module is a device that uses sound waves to measure distances. It works by emitting a sound wave and measuring the time it takes for the sound wave to bounce back. This time is then used to calculate the distance between the device and the object it is measuring.
How Does it Work with an Arduino Nano?
The Arduino Nano can be used to measure distances using an ultrasonic distance module. The Arduino Nano is connected to the ultrasonic distance module via two pins, one for sending the sound wave and one for receiving the sound wave. The Arduino Nano then sends a signal to the ultrasonic distance module to emit a sound wave. The time it takes for the sound wave to bounce back is then measured and used to calculate the distance between the device and the object it is measuring.

The code will need to include instructions to send a signal to the ultrasonic distance module to emit a sound wave and to measure the time it takes for the sound wave to bounce back.
Step 3: Testing the Arduino Code
Once the Arduino code is written, we will need to test it to make sure it is working correctly. To do this, we will need to upload the code to the Arduino Nano and then measure the distance between the device and an object. We can then compare the measured distance to the expected distance to make sure the code is working correctly.
Step 4: Calculating the Distance
Once the code is tested and working correctly, we can use it to calculate the distance between the device and an object. To do this, we will need to measure the time it takes for the sound wave to bounce back and then divide this time by two. This will give us the distance between the device and the object.
