The ultrasonic sensor is used to measure the distance.
Distance measurement using ultrasonic sensor and arduino uno code.
Ultrasonic sensor interfacing with arduino distance measurement using ultrasonic sensor.
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.
1 ultrasonic sensor hc sr04 procedure.
The high level signal is sent to 10 microseconds using trigger.
Open the arduino ide software on your computer.
