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