ABOUT THE PROJECTS

I developed and built these projects for my own use and they all work.
The technical information is minimal but you are welcome to inquire for more info.
The purpose of this website is to make a little contribution to the vast amount of free knowledge on the Internet that I benefited from.
Please don't ask me to remotely troubleshot your circuit, I can't do it. Comments about errors or improvements are welcomed.

You have rights to use, modify and distribute this software in any way you find useful, provided that you agree that I have no warranty,
obligation or liability for their contents.

B4X
Some of the projects code is in B4X, an easy to learn and to use free language for writing apps for Android, iPhone,
Arduino and Windows. https://www.b4x.com/
