Connect the ultrasonic sensor to the Arduino according to the pin configuration. (Optional) Connect the LCD display to the Arduino for speed visualization. Load the provided Arduino code into the ...

6. Connect the infrared sensor's `GND` pin to the GND pin on the Arduino. 7. Connect the `OUT` pin of the infrared sensor to pin 8 on the Arduino. ## Working - The ultrasonic sensor measures the ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

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 ...
