ULTRASONIC SENSOR ARDUINO CIRCUIT HOW TO

Echo pin of second sensor into Pin # 5 of Arduino.Trig Pin of second sensor into Pin # 4 of Arduino.Echho Pin of first sensor into Pin # 2 of Arduino.Trig Pin of first sensor into Pin # 3 of Arduino.GND of all sensors will go into GND of Arduino.Vcc of all sensors will go into +5V of Arduino.I am pointing out the pin configuration here so it will be easy for you to interface your sensors with arduino.I have tried my best while designing this image to make it simple but as there are too much wires so it has become a little complex.

So, here I am gonna use three ultrasonic sensor and the circuit diagram is shown below:.First of all, we will generate the trigger pulse for first sensor and the read its echo pin and get the distance, then we generate the trigger pulse for second sensor and read its echo pin and so on for the third.This is the process for single ultrasonic sensor and when we are using multiple ultrasonic sensors, what we need to do is simply repeat the whole procedure for all the sensors one by one.Now, in order to check this bouncing signal, we have to read the Echo pin and check for how long it remains HIGH, and on the basis of this duration we calculate our distance with the object.This ultrasonic signal then hits something and bounced back.As soon as the ultrasonic sensor gets this trigger signal, it sends out an ultrasonic signal.

With ultrasonic sensor, what we need to do is to generate a trigger signal on its trigger pin for around 10 microsecond.

Let me first summarize the working of ultrasonic sensor again.

Moreover, for hardware implementation of Ultrasonic Sensor with Arduino, check below posts:.

I have also posted more examples on Ultrasonic Sensor Simulation in Proteus, have a look at them and you will get complete understanding of this sensor.

Other Proteus Libraries are as follows:.

Now, let's get started with Interfacing of multiple ultrasonic sensor with arduino, which isn't that difficult. If you haven't read it then I recommend that you should first read Interfacing of Ultrasonic sensor with Arduino. I have posted about the basics of Ultrasonic sensor and how it works in my previous post so I am not gonna go into that detail.

ULTRASONIC SENSOR ARDUINO CIRCUIT HOW TO

So, in short its a common practice to use multiple ultrasonic sensor with Arduino and today we are gonna have a look at how to do it. In that case, I also used two ultrasonic sensors on both sides of robot and then applied PID algorithm in order to avoid hitting the walls. Similarly, in another project I have to move the robot in a maze having walls on the side of robots, and my task was to move the robot straight within these walls without hitting the walls. For example you have an obstacle detection robot, now in order to detect obstacle in front of robot you have to place once sensor on the front side but now you can't detect any object present on left or right side of your robot, so you have to place two sensors one on the left side of robot and one on the right side so in this project you need to use total three ultrasonic sensors, one on the front, one on left and one on right side of robot. In the previous post, we have seen Interfacing of Ultrasonic Sensor With Arduino and in this post I have interfaced single ultrasonic sensor but in projects especially related to robotics, we have to interface multiple ultrasonic sensors. Today, I am gonna post about interfacing of multiple Ultrasonic sensor with Arduino.

Hello friends, hope you are having fun and enjoying life.
