Arduino Ultrasonic Sensor Newping

Go back look right look left and go where it is clear. The reaction of the car to an obstacle is.

Unlike the ultrasonic distance sensors weve used previously these devices are waterproof.

. We have used the HC-SR04 Ultrasonic Distance Sensor many times here in the DroneBot Workshop and for many good reasons. Include standard library for the servo include for the. We will be using the NewPing library to get the distance value from the sensor.

It is pretty easy to use it performs well and it is very inexpensive. It has four pins namely Vcc Trig Echo and Gnd. The ultrasonic distance sensor that Ive used is the US-020.

If both sides are clear it will go forward. The maximum distance between the car and an object is set in the code and the reaction of the car too. We will read the distance once every.

You need the New Ping Library for the ultrasonic sensor. The trigger and echo pins are respectively connected to digital pins 9 and 8 of Arduino. It is powered by a 5V source.
