Circuit is very simple for this Obstacle Avoiding Robot using Raspberry Pi. When the sound emitted by the sensor reflects off of an object and returns to the sensor, the sensor sends a digital signal to the Arduino. Instead of using a single ultrasonic sensor to solve the sensing problem, we made use of three sensors to guide the robot in a complex environment. Obstacle Detection using Ultrasonic Sensors Prof. D. S. Vidhya Miss Delicia Perlin Rebelo Assistant Professor (Guide) UG Student Department of Electronics and Telecommunication Engineering Department of Electronics and Telecommunication Engineering Don Bosco College of Engineering, Fatorda, India Don Bosco College of Engineering, Fatorda, India In such a case, a high path accuracy cannot be achieved. Ultrasonic sensors not only offer distance measuring utility without any physical contact but enable us to measure with no noise and light, unlike laser-based distance measuring instruments. /* This code should work to get warning cross the buzzer when something be closer than 0.5 meter.
