View Wall Follower Robot Using Arduino And Ultrasonic Sensor Gif. Line follower robots usually equip color sensors to differentiate between the line they are following and the the ultrasonic sensor will be placed on the front of the robot. Gnd pin is connected to the ground.
Here's another example how to use the ultrasonic sensor with arduino and display the results on an lcd. Line following robot using ir sensors has become trendy for beginners and for those who have an interest in making projects and new things. Today, i am gonna post about interfacing of multiple ultrasonic sensor with arduino.
One ultrasonic sensor is mounted on the left side of the car and another mounted on the front of the car.
What sensors are you using for line detection and how many are they? Trigger pin of ultrasonic sensor is connected to pin no. I searched most of the documents, but they didn't solve our problem. Gnd pin is connected to the ground.
