TVZ Mechatronics Team / Mbed 2 deprecated HC-SR04

A program that demonstrates the development of library, using as an example an ultrasonic distance sensor HC-SR04.

Dependencies:   mbed HCSR04 AutomationElements

The purpose of this program is to encourage students to develope their own classes. Instructions how to follow the development of this program and class HCSR04 for ultrasonic distance measurement are given here.
