Library for hc sr04 ultrasonic distance sensor.
Hc sr04 arduino beispiel. How to plug the ultrasonic hc sr04 into the arduino using the example plugandplay. In particular a switch statement compares the value of a variable to the values specified in case statements. Open a new sketch file by clicking new.
In this project the ultrasonic sensor reads and writes the distance to an object in the serial monitor. Not wanting to concede i had a doa sensor on my hands i searched for a simple example setup. After buying a hc sr04 from amazon i could not get it to work out of the box.
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. 1 arduino uno r3. Simple arduino and hc sr04 example.
So here we provide an example on how to use the hc sr04 ultrasonic sensor with the arduino. Repository contents firmware arduino example code. Arduino with hc sr04 sensor.
You will learn how to interface ultrasonic sensor hc sr04 with arduino. Things used in this project. Ardublog mi blog en español sobre arduino ardublog libreria para arduino del modulo ultrasonic ranging hc sr04.
When a case statement is found whose value matches that of the variable the code in that case statement is run. Library for hc sr04 ultrasonic distance sensor. Ultrasonic sensor hc sr04 ultrasonic sensor hc sr04 sen 15569 this is the hc sr04 ultrasonic ranging sensor.
