Arduino and artificial intelligence2

• We have spoken in our first article on the painting Arduino and its types.

• In this article we will talk about some sensors that can be linked to the Arduino panel.

• The picture below shows a set of sensors that have multiple uses depending on the project you want to set up
  

• In this article we will focus on the sensor "HC-SR04"/ "Ultrasonic".
  1- Definition of Ultrasonic Sensitivity:
  Ultrasonic sensor is a sensor that works on principle similar to radar or sonar. It generates high frequency sound and calculate the time interval between the sending of signal and the receiving of echo. Therefore, ultrasonic sensor can be used to measure distance. HC-SR04 ultrasonic sensor consists of a transmitter, a receiver and a control module.
  2- How to use with the Arduino?
• The picture below simply shows how to connect the sensor with the panel.
• The issue is simple and simple. It is only a matter of entrances and exits.
  

3-How it works?

• The sensor transmits chirp waves every short period of time. When these waves collide with a sensitive buffer, they pick up the sensitive echo again with the Arduino plate, which in turn calculates the distance between the robot and the barrier, as in the robot design example.
  The picture below shows the process well
  

4- Uses of Sensor?

• The Sensor has many uses and many are mentioned in the field of artificial intelligence:
  - Robotics
  -Radar.
  -System Alarm
  -Smart House
  -Smart Car
  

/I think I will stop at this point so that the subject will not become boring and we will continue in the next article with other sensor - thank you
