Calculating distance with the HC-SR04

A few days ago we published an article talking about Module HC SR04, and how important is to  robotics and Arduino projects, so today I bring a test of this module, which will test a small code to measure the distance at which it is an obstacle. Recall that the measurement range of this module is from 2cm to 400cm, so we will put to test  an […]

HC-SR04 Sensor

The HC-SR04 sensor has become very popular among users of Arduino, because its easy implementation, is one of the most used modules in robotics. The HC-SR04 sensor is an ultrasonic sensor that detects obstacles in front of him, from a minimum distance of 2cm to 4m, operating at a frequency of 40Khz, has a measuring angle of about 15 degrees. It has an entry called […]
