Ultrasonic Sensor Arduino Project Code

340 meters per second.

Ultrasonic sensor arduino project code.

We will use the serial monitor with this line of code. Simple project with the ultrasonic sensor hc sr04 led arduino tutoriel. Now load the code in arduino ide and then upload it to arduino. Distance measurement using ultrasonic sensor.

You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Connect the trigger pin to pin 12 and echo pin to pin 13 of 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. 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.

Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm. Speed of the ultrasounds. In this project i will introduce you to the hc sr04 ultrasonic sensor. 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.

Select the port i e com3 and choose your arduino board type i e arduino uno genuino then compile it to your arduino. Find more about the working of distance measurement project in this tutorial. It works by sending sound waves from the transmitter which then bounce off of an object and then return to the receiver. Ultrasonic sensor hc sr04 with arduino code for ranging testc c write your code in arduino ide software save it.

Find these and other hardware projects on arduino project hub. The setup is now ready. Connect the positive terminal with pin 8 of arduino and negative terminal to gnd. The modules includes ultrasonic transmitters receiver and control circuit this is a simple example of using the ultras.

Connect the vcc and gnd. A 16x2 lcd is used for displaying distance. This is proect of arduino 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.

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. Connect gnd with gnd on arduino. Arduino ultrasonic sensor code for distance measurement. Check the serial monitor readings.

Connect echo to digital pin 6 on your arduino board. Connect trigger to digital pin 7 on your arduino board.
