Years ago a colleague of me told me about Arduino. He had made an application for Ambilight based on Arduino. For the making of little controls for the annual village festivals, I was looking for some sort of simple PLC for building it and an Arduino board seems a good alternative. So I bought a MEGA 2560 and made my first sketch in 2012; It was an application for a game that counted the most possible turns a person can make around a rod during 30 seconds. The results were presented via a laptop; rounds, high scores, time to go... Making rounds -around a rod- can do funny things for a men’s brain... Making the sketch was also fun to do, everything worked fine and most imported it was stable. Arduino seems to be a platform ideal for hobby. First years of my working period, about 15 years, I had a job in IT and after that I became project manager at a system integrator. I kept my interest for programming and specially controls. So, during rainy days, I started building software for a finite state machine on the Arduino platform and made this site as a hobby. The site describes part of terms and techniques used in the automation of (industrial) controls and can be used for hobby (specially Arduino/Visual Studio) but also for understanding some basic PLC and HMI techniques. Enjoy this site and feel free to contact me.
