Step 1: Connecting the SR04 Ultrasonic Sensor to the Arduino Here in the picture Trig and Echo is connected to 12 and 11 But according to our code we have connected trig to 13 and echo to 12 . So be ...

Here we discussed about the pinout and different modes of ultrasonic sensor module and how it works. Also we learned how we can use ultrasonic sensor module with Arduino.

The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

ultrasonic sensor value in lcd display with arduino ultrasonic sensor value in LCD display with Arduino code: // C++ code // include the library code: #include // initialize the library with the ...

HC-SR 04 Ultrasonic sensor is most commonly used to measure distance, but this time I will show you how to measure the speed of movement of an object using this sensor. Device is very simple and ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.
