If we want the get the distance result in cm, we can convert the speed of sound value from 340m/s to 34cm/ms. Distance = (Speed x Time) / 2 = (34cm/ms x 1.5ms) / 2 = 25.5cm. So, if the Echo pin was ...

Ultrasonic Module with Arduino Connection Diagram. The Following connections are made between Arduino UNO and the Sensor: Arduino Code. As discussed in the working section, we need to send 10uS pulses ...

The ultra sonic circuit is adjusted in such a way as to stay in balance as long the same as the output frequency of the transmitter. If there is some movement in the area covered by the ultrasonic ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...
