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 ...

Also we learned how we can use ultrasonic sensor module with Arduino. ... article also discusses the working of the module along with a detailed explanation of the code required to process the data ...

Smart Blind Stick using Arduino Circuit Diagram. The below circuit diagram shows the complete hardware wiring setup of the Arduino-based Smart Walking Stick for the Blind people, detailing how the ...

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 ...

Serial Plotter is an amazing tool available in Arduino IDE (from v1.6.6) to visualize the “returned” data beyond just seeing numbers spit out onto the traditional serial monitor window. The Arduino ...

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 ...
