The provided Arduino code performs the following actions: Initializes pins and serial communication. Measures the distance using the ultrasonic sensor and calculates the distance in centimeters.

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 ...

Now, the venerable ultrasonic sensor joins the gallery of classics given a size change treatment, like the 555 timer we’ve seen two different takes on, or perhaps that one Arduino Uno.

The traditional single sensor alarm system has been difficult to meet the requirements of multiple pollutants detection at the same time, so this research proposes a multi-sensor integrated ...

The design of a “third eye for the blind,” which employs ultrasonic waves to detect surrounding obstructions and notify users with a buzzer sound or vibration, is made feasible by the collaboration of ...
