electric current (AND, OR, XOR, NOT)

[DivideByZero]

How can I make AND, OR, XOR, and NOT logic gates in an electric current.

 

The power source could be a battery and I can connect parts using a copper wire.

 

But how can I make these logic gates? Whats the simplest way?

[Klaynos]

The simplest way would be to buy some logic gates

 

Or buy some transistors and follow a circuit diagram for the gate you want, there are alot around online, do a quick google.

Well, I'd like to build my own as oppose to buy one. How hard can it be to build an OR gate anyways?

 

I'm mainly doing this for educational purposes. Once I get used to it, I might start buying pre-made logic gates.

 

I really want to make my own! Help!

Diodes and a resistor can be used for OR and AND gates. I found this, it might help.

Oh my! Thank you guys so much!!!!

You can also use relays to do this sort of thing. They are a bit slow.
