The HC-SR04 ultrasonic sensor uses SONAR to determine the distance of an object just like the bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy ...

Radar-Using-Arduino-Uno-Ultrasonic-Sensor The Arduino Uno R3 Compatible Board is a microcontroller board that is based on the ATmega328. Arduino Uno has 14 digital input or output pins (where 6 can be ...

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 ...

The Arduino keeps on processing the data from the ultrasonic sensor, and it quickly triggers the Audio alert when it detects something nearby. Here, you’ll learn how to interface the ultrasonic sensor ...

Ultrasonic sensors are used to detect the presence of obstacles, calculate the distance to these obstacles, and relay this information to the driver through visual and auditory cues. This research ...
