This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

Ultrasonic sensor powered by Arduino UNO The servos should not be powered by the Arduino directly due to insufficient current supply, which could damage the voltage regulator. Instead, an external ...

WORKING VIDEO: human-following-robot.mp4 Conclusion: Building a human-following robot using Arduino and three ultrasonic sensors is an exciting and rewarding project that combines programming, ...

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 ...

With a standard old HC-SR04 ultrasonic sensor, an audio module and a servo to drive a custom gauge needle he’s made a device which can warn people around you if they’re too close for comfort.

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 ...

A simple robotics project simulated in Tinkercad based on Arduino Uno. It uses ultrasonic sensors for obstacle detection and can do basic movements using DC motors. The primary objective of this ...

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 ...
