I've done so much research on this but I can't find anything. What kind of wire do I use for DIY electronics, and for hobby purposes? For example, if I was making a simple robot with rPi, what kind of wire do I use (stranded vs solid, gauge, metal composition, etc)?

Also, I would really appreciate if you could tell me where to purchase the wire
 
Solution
Stranded copper wire? The gauge just depends on how long the wire needs to be and how much current it has to carry; there's gauge recommendation charts online.
