tin-plated copper.

You're not supposed to run breadboard wires around corners. You're supposed
to plug it into a hole and run a connected wire at an angle if you need angles.

I don't follow.

See how the black cable goes from C1 to C2?
Or how the purple cable goes "around the corner"?

I see...
Makes it kinda hard to rest the ends of the wires on both battery
terminals simultaneously when they're utterly rigid though. Similarly,
if you've got one wire that's 4 holes wide and another that's 6 holes
wide, you have to systematically design your circuits to not need any
connections 5 holes wide. Routing becomes formally equivilent to solving
the Zero Sum problem. (!) Not to mention the fact that those tiny 1-hole
wide wire loops are excruciatingly hard to manipulate.
By contrast, if you have some flexible wire, you can make a loop of any
size you desire, and it's very easy to work with.

Would it work if each switch had a seperate resistor? Or does that not
fix it?

>> Hmm, this isn't going to work at all, is it?
Depends what you mean by "work". Seems like the two input pins on the IC
are actually tied together (to the top side of the resistor), so it's just
going to work like a NOT gate.
Did you also do the calculations to check that it's ok to use a single 360
Ohm resistor with those two LEDs for every combination of output states?

Dude, really, you are going to fall over yourself over and over again if you
refuse to learn at least some basic analogue circuit electronics. You must
have realised by now that even to implement the simplest logic circuits you
absolutely must have some basic level of understanding.
Also try to draw your circuit schematics the same way as others do (you will
pick this up automatically whilst you learn about them, eg ICs like this are
usually drawn vertically, not horizontally). Others will be more likely to
help you if they don't have to spend time deciphering which wires are
connected to what.

It is meant to be like that, so you can plug it straight into the
breadboard. If you really need to bend it then get a pair of needle nose
pliers and make a neat bend. Those pliers are also very useful for plugging
in and removing the very shortest wires.

That's what battery holders are for.

So what you're saying is that there is basically no way I will ever get
this to work, and I should just give up now?
