Has anyone done any amount of Python programming on an Arduino? I have been fooling around with an Arduino Nano on a Mac. I got the ubiquitous 'Blink'...

Every operating system I know of comes with a built-in calculator these days. Smartphones as well. This program was more of a chance to re-live my d...

Such as it is. My first "toe in the water" with Python programming: I have tested it on Debian-11 (on a Pi 4) and Ubuntu 22.04 with an Intel CPU...

Otherwise, I can build a Rube Goldberg machine. Rheostat to play with the 120 V in to lower it to 80-90 volts. Then feed that into the 120 --> 240 ...

The P = I * V one gets his walking papers! I knew there was more to this. No idea if the element is the same resistance. I think I'll give up on th...
