The Ultrasonic Sensor – Open-source Arduino Robot Building ...

The ultrasonic sensor measures distance. One of the “eyes” transmits a sound, and the other waits for the echo of the sound to return. From the time this process takes, the distance of the object from the sensor can be calculated. The ultrasonic sensor has a range of 3-400cm. If an object is outside this range, the sensor will return a value of 400. In this lesson, I want to get the robot ...

Ultrasonic Sensor Test Code | TechLabs

When the robot is plugged into your computer, and you have an open serial monitor (select “Tools” from your Arduino IDE menu), you will see a continuous stream of output in the monitor describing the distance (in CM) of an object in front of the robot’s ultrasonic sensor (eyes): // Ultrasonic sensor pins #define echoPin A0 #define pingPin 3. void setup() {// put your setup code here, to run once: (9600); // ultrasonic sensors …

Ultrasonic Sensor HC-SR04 with Arduino Tutorial -

Ultrasonic Sensor HC-SR04 is a sensor that can measure distance. It emits an ultrasound at 40 000 Hz (40kHz) which travels through the air and if there is an object or obstacle on its path It will bounce back to the module. Considering the travel time and the speed of the sound you can calculate the distance. The configuration pin of HC-SR04 is ...

How to Use an Ultrasonic Sensor - Arduino Project Hub

This project will show you how to use an ultrasonic sensor with an Arduino. What is an ultrasonic sensor? An ultrasonic sensor is a module which uses ultrasound (you didn't expect that, did you?). It allows to detect a presence or to measure a distance via ultrasounds. He sends an ultrasound pulse via his trig terminals and receives them via his echo terminals. The ultrasonic sensor sends 8 ...

use Ultrasonic sensor to test the rotating speed - Arduino

· Hello, I am a new one on arduino. I am doing a project to test a horizontal spinning bar spinning speed (rpm) by using an ultrasonic sensor. The ultrasonic sensor will be above the bar, and face the bar. My basic principle is that when the bar does not appear in the realm of the ultrasonic sensor, the distance measured by the ultrasonic sensor is a certain value.
