The Arduino is a circuit board that you'll program to perform certain tasks, and what it does will entirely be up to you. You can make it do all sorts of things, ranging from creating a smart ...

(Hint: there’s no Arduino-provided code involved; hardware registers and the __asm keyword show up.) If you learned embedded programming in an earlier era, this will probably seem glaringly obvious.

As explained by Arduino to Go, ... Parsing various resistor band colors is fairly simple once you know what each color means. Orient the resistor with the gold or silver band on the far right.

While we have seen other Arduino based constant loads before, [Jasper’s] is very simple and straight forward compartively. [Jasper] also includes both the schematic and Arduino code, making it ...
