How the Arduino ultrasonic sensor actually works. To measure distances with Arduino we can do it in different ways. There is the infrared sensor, which uses the properties of light to calculate ...

The HC-SR04 sensor is a Ultrasonic sensor. we can not use this sensor direct in a circuit. We need a microcontroller for communication with the sensor. I use arduino in this case. The HC-SR04 ...

The set-up process is very simple, and best understood by referring the wiring diagram. If everything goes right,you should see the burning eye of the red LED when there is no object in the safe-zone ...

The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

In Electronics, most of the time Ultrasonic Sensors are used to measure the distance from one particular point to another. It is very easy to write a code on the Arduino board and integrate an ...

FactoryReset - Reset the all the value to standard of Ultrasonic Sensor register. ReadBaudrate - Read the communication data rate of the Ultrasonic Sensor. ReadDistance - Read the distance measure ...

Ultrasonic Sensor; Buzzer; Arduino Mega (any model) Jumper Wires; USB cable for Arduino or 12v, 1A adapter. Ultrasonic Sensor Module: Ultrasonic sensor HC-SR04 is used here to detect the presences of ...
