Ultrasonic Sensor Arduino Project Code
Speed of the ultrasounds.
Ultrasonic sensor arduino project code. This is proect of arduino ultrasonic sensor. Connect the positive terminal with pin 8 of arduino and negative terminal to gnd. Ultrasonic ranging module hc sr04 provides 2cm 400cm non contact measurement function the ranging accuracy can reach to 3mm. Now load the code in arduino ide and then upload it to arduino.
Ultrasonic sensor hc sr04 with arduino code for ranging testc c write your code in arduino ide software save it. Find more about the working of distance measurement project in this tutorial. The setup is now ready. Select the port i e com3 and choose your arduino board type i e arduino uno genuino then compile it to your arduino.
You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. Distance measurement using ultrasonic sensor. Check the serial monitor readings. We will use the serial monitor with this line of code.
It works by sending sound waves from the transmitter which then bounce off of an object and then return to the receiver. Connect gnd with gnd on arduino. Serial print distance in cm. 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. 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. A 16x2 lcd is used for displaying distance. In this project i will introduce you to the hc sr04 ultrasonic sensor.
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. The modules includes ultrasonic transmitters receiver and control circuit this is a simple example of using the ultras. Arduino ultrasonic sensor code for distance measurement. Connect the vcc and gnd.
Connect echo to digital pin 6 on your arduino board. Find these and other hardware projects on arduino project hub. 340 meters per second. Connect trigger to digital pin 7 on your arduino board.
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. Simple project with the ultrasonic sensor hc sr04 led arduino tutoriel.
