Eclipse is a kind of universal tool platform - an open extensible IDE for anything and nothing in particular. The real value of Eclipse comes from tool plug-ins that "teach" Eclipse how to work with things - java files, web content, graphics, video, etc. Eclipse allows you to independently develop tools that integrate with other people's tools seamlessly.
HC-SR04 Ultrasonic Arduino Library is specifically for the HC-SR04 ultrasonic sensor. It features timing, metric conversion, and standard deviation methods, plus a few support methods. It is written in C++ to conserve the namespace. The conversion formula can be easily modified to optimize the accuracy of conversion at different distances for inches and centimeters. Multiple buffers of different lengths can be created for determining standard deviation.

The user can add smiles in chat, and can format the text with Bold, Italic, an Underline.
