An adder (in electronics) is basically a circuit that takes three bits (0 or 1 numbers) and returns the number of 1s in binary. It's the basic component in larger circuits that add binary numbers (hence, adder).
The circuit that I made today does this. You can see that all three switches on the right are up, and that two green LEDs on the right are on. That is, 11 = 3 in binary. You have to believe that it works, though. The chip on the left is complicated.
And yeah, I'm posting another electronics wiring. I should have taken a picture of the squirrel sign, or something.
Wow, it makes me think of cascades in cell signaling and neuronal circuitry. Haha.
