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 ...

In this project we are going to discuss how to use Ultrasonic sensor (Distance /Range Finder) with arduino micro-controller .We will be getting the object distance or range of an object on the Serial ...

Once the code is compiled and uploaded on the Arduino, open the Serial monitor to view the output of the system. Note: If the system does not give correct output or gives erratic readings, adjust the ...

The ultrasonic sensor acts as the input and the servo motor acts as the output, the Arduino UNO microcontroller is the main brain behind the project. ... we start the serial monitor at 9600 baud rate ...

Fig. 4: Timing diagram of ultrasonic sensor. Compile and upload this code to Arduino Uno. Open Serial Monitor under Tools of Arduino IDE to see the sensor output (distance between sensor and object).

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 ...

In this review of the Maker Uno RP2040 board with the Arduino IDE we could blink LEDs, control RGB LED lights, press the user button to turn on one LED or make the buzzer output some melody, control a ...

To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...
