Application: Fuzzy Logic Image Processing

The same MATLAB code at [LINK] is applied with a change of image only. Both input and output are shown below for record.

Example 4-1 from Make: AVR Programming (2014)

This post is based on classroom demonstration of Example 4-1 from book Make: AVR Programming by Elliot Williams. The demonstration has three variations in cylonEyes.c listing on pp. 60-61. The Proteus simulation model is shown below. Then comes program codes and a short movie clip.

Presentation: An Introduction to LaTeX for Engineers and Scientists

Finally, the initial version of this presentation is ready. This is an introduction level presentation on LaTeX -- the professional document preparation system. In addition to this presentation, I have created a project on overleaf for a practical demonstration. There are many useful online resources, my choices for interested LaTeX learners are Free & Interactive Online Introduction to LaTeX (three parts by Dr. John Lees-Miller) and TeXample.
