Ultrasonic Sensor Arduino Project Code

We will use the serial monitor with this line of code.

Ultrasonic sensor arduino project code.

Connect the vcc and gnd. 340 meters per second. Connect trigger to digital pin 7 on your arduino board. A 16x2 lcd is used for displaying distance.

Connect the positive terminal with pin 8 of arduino and negative terminal to gnd. In this project i will introduce you to the hc sr04 ultrasonic sensor. Find these and other hardware projects on arduino project hub. Find more about the working of distance measurement project in this tutorial.

Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm. The setup is now ready. Where speed of sound around 340m per second. This is proect of arduino ultrasonic sensor.

Connect gnd with gnd on arduino. Distance measurement using ultrasonic sensor. But what you will get from the echo pin will be double that number because the sound wave needs to travel forward and bounce backward so in order to get the distance in cm we need to multiply the received travel time value. The ultrasonic sensor has four terminals plus 5v trigger echo and gnd connected as follows connect the plus 5v pin to plus 5v on your arduino board.

Check the serial monitor readings. Connect echo to digital pin 6 on your arduino board. Speed of the ultrasounds. The ultrasonic pulses collide an object and leaves in the other direction the echo terminals receives the ultrasound pulses and the sensor calculates the distance based on the time of the pulses.

Now load the code in arduino ide and then upload it to arduino. Arduino ultrasonic sensor code for distance measurement. The modules includes ultrasonic transmitters receiver and control circuit this is a simple example of using the ultras. Explore 68 projects tagged with ultrasonic.

You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Ultrasonic sensor arduino not only offer distance measuring utility without any physical contact but enable us to measure with no noise and light unlike laser based distance measuring instruments. It works by sending sound waves from the transmitter which then bounce off of an object and then return to the receiver. Connect the trigger pin to pin 12 and echo pin to pin 13 of arduino.

Select the port i e com3 and choose your arduino board type i e arduino uno genuino then compile it to your arduino. For example if the object is 20 cm away from the sensor and the speed of the sound is 340 m s or 0 034 cm µs the sound wave will need to travel about 588 microseconds.
