LogicGates-MechanicalComputer app analytics for March 28

The basic principle of a computer is a combination of some switching circuits. The light switch that we normally use is a switching circuit, and the computing chip uses a very large number (currently hundreds of millions) of circuits to achieve a fast computing function. This APP is to introduce how to use some switch circuits to achieve an addition function. This is also the basic principle of logic gate, after understanding the basic principle, maybe you can make CPU by hand.
