Obstacle sensor using Arduino and HCSR04
BuildCircuit has previously published a project on HCSR04 ultrasonic range finder module. You can checkout the article from this link.
Now, we have another article on HCSR04. It is as simple as the previous project.
HCSR04 ultrasonic range finder module: The HC-SRO4 is an ultrasonic sensor which uses sonar to detect objects at a distance of 2 cm to 4 meters. This sensor is widely used in robotics to build robots that move and should divert or avoid obstacles. You can read more about this module on this article. (more…)
