This uses Arduino MEGA connected to a Ultrasonic sensor and and I2C LCD screen to display distance from the sensor This code will check distance and indicate if an obstacle/person is away for 5 ...

This project uses an Arduino to measure distance using an HC-SR04 ultrasonic sensor and displays the result on a 16x2 LCD screen. The sensor sends out ultrasonic pulses and calculates the distance ...

Here is the schematic diagram of a Human-following robot circuit. This design incorporates three ultrasonic sensors, allowing distance measurements in three directions front, right, and left. These ...
