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 ...

The sensor continuously sends out infrared light and measures how much of that light is reflected. When a reflective object is within its set detection range, it returns a low signal. The Arduino ...

In this Project I tryed to use my Arduino to measure the distance. For this I used as I sayed my Micro Controller (You can use every Micro Controller, even one without WLAN), an Ultrasonic Distance ...
