The ultrasonic sensor with Arduino allows us to measure distances through ultrasound. It is very common to find this type of sensor in today’s cars. The objective is to show how we can build real ...

Ultrasonic Sensor Module There are many types of Arduino distance sensors, but in this project we have used the HC-SR04 to measure distance in range of 2cm-400cm with an accuracy of 3mm. The sensor ...

Human Following Robot Using Arduino Code Here is a simple 3 Ultrasonic sensor-based Human following robot using Arduino Uno code that you can use for your project. This code reads the distances from ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...

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 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 ...
