Logic Gates

AND logic gate
This will only be activate if both switches are true or both are false, they have to be the same.
















 OR logic gate 
This logic gate will only activate if the inputs are different and not the same except if they are both true or 1 then it activates too. So true and false or false and true wouldn't turn it on.





















NOT logic gate 
This logic gate will reverse any input, so a false would become a true or a 0 would be a 1.







 












XOR logic gate
Xor gates only turns on if the inputs are different so it's like a stricter OR gate.



















NAND Logic gate
 It will activate when both inputs are turned to false/0 or if the inputs are different. Its a combination of AND and the NOT logic gates.





















NOR Logic gate
This is like to the NAND gate as it turns on when the inputs values are both false but it won't activate if the inputs are different or both true.

  1. Good summary - you could also add in a bit about boolean algebra and how to simplify boolean equations
