+ | The sky blue version is ugly, so I bought a new one in transparent. This looks nice. Also I finally found time to put some oil on the wood. This also looks nice. The project is finished now and I am happy with it. Will upload images later. | ||

I know I can build an AND gate from one relay. But in this preproject I build it from two. It is easy to explain how it works this way. | I know I can build an AND gate from one relay. But in this preproject I build it from two. It is easy to explain how it works this way. | ||

The OR gate is very simple. As High is 5V and Low is floating we can just connect the wires to get the or logic. | The OR gate is very simple. As High is 5V and Low is floating we can just connect the wires to get the or logic. | ||
