I have been interested in electronics since being a young teenager, making electronic projects for the electric guitar. then learning to program PicMicrochips and the ZX81 using machine code.  After an absence of a decade or so I started to get back into it using the Raspberry Pi (I have one of each of the 40 pin versions) and later with the Arduino Uno and Nano.  I enjoyed Craig Hollinger's series on programming the Arduino and then found Bills website.  As I'm also interested in building and flying model aircraft and drones I was immediately hooked.  However still in a physically very demanding job the visits have been infrequent, now retired I intend to correct that and will become more fluent in programming hopefully with help from the forum.
