This Arduino-based distance meter can be used for measuring the distance between the sensor and object in the range of 2cm to 400cm using an ultrasonic sensor.The author’s prototype and ultrasonic ...

As shown in timing diagram above, the Echo pin will stay low till the wave return back and will then go high and stay high for the exact time taken for the waves to return back. ... Arduino & ...

Circuit Diagram: To control the PC with Hand Gestures, just connect the two Ultrasonic sensors with Arduino. We know US sensor work with 5V and hence they are powered by the on board Voltage regulator ...

In this project, the ultrasonic sensor module type KY-050 is used together with an Arduino and a type KY-012 active buzzer to help while reverse parking our vehicle. As the distance to the objects ...
