Step 2Build the Circuit
The circuitry here is pretty simple, it's just so that you have a light and a switch. Note: the switch is not represented in the circuit diagram. If you don't know how to add the switch yourself, then you should probably not attempt this at all. Sorry.
Yes, I know that the LED doesn't come on under 1.5v, and that it's dim at 3v and 4.5v, but I rarely use below 3v, and I know that if I don't have a light to remind me I'm going to leave it on. I could have just used a variable regulator for this project, and then used the 5v regulator solely to power the LED, but in Montreal all of the RadioShacks have been bought out by this dumb store called "La Source", which appears to have higher prices and no electronic components. Anyway, that's just my opinion (La Source, please don't sue me). I bought these components last time I was in Plattsburgh, before I though of this project.
If anyone knows of an electronic components store in Montreal, please drop me a line in the comments. I appreciate it.
