The
HC-SR04
or
the
ultrasonic
sensor is being used in a wide range
of electronics projects for creating
obstacle
detection
and
distance
measuring application as well as
various other applications. Here we have brought the simple
method to measure the distance with arduino and ultrasonic sensor
and how to use ultrasonic sensor with arduino.
