I'm just your typical poor college kid living on ramen noodles. I'm a Computer and Electrical Engineering major so one can only imagine the levels of nerdom reached behind the door of my apartment. I also work in tech support at a electronics store, arming me with endless stories of funny and horrific technology mishaps... So tune in and enjoy nerd blurbs, random ideas, and funny stories.

Anonymous asked: I know ground and power are different, put the colours (yellow, blue, purple, etc) dont matter, right?
They each are carrying a different signal to perform a function that was designated by the designer but if you were talking about completely taking everything apart and disconnecting each wire from each end then I guess it wouldn’t matter what color you used to rewire it. Unless the kit you’re talking about came not assembled with just a bag of random wires for you to use, if that’s the case you can use whatever color you want for whatever, just be wise about it.
Anonymous asked: because I saw on the internet this kit with 5 colours of wires but I didnt know what to do with that...
You need to find the schematic wiring diagram for that particular kit, that will tell you what the colors denote.
Anonymous asked: so they are basically the same thing?
Not really sure what you’re asking I’m afraid.… Ground and power are definitely not the same thing. The physical wires are the same type of wire but what signal/voltage they are carry is different which is denoted by the different colors.
Anonymous asked: do u know the difference between the colours of the wires? not the black and the red ones, the others... thanks
As a general rule of thumb black is ground and red is power but if you’re the designer you can make them whatever you want. It’s the same concept as filing papers with different colored sticky notes, the colors can mean whatever you want as long as you know what you’re doing. My robot looks like rainbow spaghetti just because I ran out of colors!
Detection of obstacles: if there’s no open pathway to its left as it drives along a wall it will keep driving forward and as soon as it sees an opening/doorway it will stop and turn into that opening. (It is up on a block so we could test it without chasing it lol)
Anonymous asked: where did u learn how to program arduino? I tried some websites but I don't really get it :/
It’s a weird hybrid of C and C++, there are tons of tutorials online.
Anonymous asked: and about the breadboard, how do u know where each thing goes? I mean, there are so many holes, you could just put the things anywhere........
I’m not really sure what to tell you, I think you need to start researching and studying basic circuit theory first, along with some C++ programming.
Anonymous asked: I was thinking about making an infrared sensor that turns the LEDs on when people get closer, but I want to make it with a LED strip, but I only know how to make with just one LED...
I have a one word answer for you: multiplexer.
