Hi Everyone,
I program night and day - have been for 30+ years - but I have literally never handled a breadboard before. I’m working my way through the tutorials, but they seem to assume a certain level of pre-existing competence with hardware.
For instance, in the temperature-sensing beginners project, there is a component set into pin J19 running off the top of the board. What is it? It’s blue in the picture. I got the starter kit from Make magazine and have spent hours reading about what the pieces are, but none of them are blue, and there’s no description of the component in the tutorial.
I know how naive this is, but I’m betting other programmers are also picking up the electronics they’ve programmed for years but never before handled.
Programming in whatever language doesn’t bother me a bit - figuring out which-wire-gets-shoved-where is giving me fits!
Please post here any suggested sites on beginner electronics, and what is that BLUE THING?!
