When you change the value of a potentiometer or activate an infrared detector, it changes the value transmitted by the cables. Look carefully at the values displayed in the bottom right tooltip, which allows us to know the value carried by a cable.
At the end of the video, we see all the logic gates that allow to manipulate these values. They are divided into two categories.
Logic gates of the first category are put on the top line in the video. They return either 0 or 255, but not an intermediate value.
Logic gates of the second category are put on the bottom line. They return a number between 0 and 255.
It begins to become interesting, isn’t it? Wait to see the next episode!
