Welcome to this video on Arduino Tutorial for Beginners. This video about Sonar Module (HC SR04) Ultrasonic Distance Sensor With Arduino.
This video shows how Sonar module work
The sonar module will transfer wave to object and then receive that reflected wave again . And we will base on this way to calculate the distance between object and module.
About TIME :
We call time transfer from module to object is t1
We call time receive echo wave from object is t2
Two time is approximate equal , so we can get the TIME = (t1 + t2 )/2
About SPEED :
The speed of sound is around 340-359 in our air, so i will take average is about 347.5 m/s
we will convert it to cm/us on google or divide be 100000 ,And we can get the SPEED
About DISTANCE:
Base on the formular , we have DISTANCE = TIME * SPEED (cm)
We can use the method above to get the distance or use the library on the internet
----------------------
Code :
pulseIn(_pin,HIGH)
This fuction will retrurn a INTERGER value of HIGH time in a pulse
pulseIn(_pin,LOW)
This fuction will retrurn a INTERGER value of LOW time in a pulse
Arduino programs, called “sketches”, are written in a programming language similar to C and C++. Many sensors and other hardware devices come with prewritten software – look on-line for sample code, libraries (of functions), and tutorials. Learn the Arduino platform and programming language to create robots, interactive art displays, electronic gadgets and much more.
