There are times that you will surely need to send a signal to more than one place, and for this there are multiples, which will be very useful to route your signals, finding 2 types, passive and buffered.
PASSIVES: Basically a group of connections connected to each other without circuits between them. Connect your signal to one of the shots and take copies of the other shots.
BUFFERED: Copy the voltage from an input connector to an output connector. Since there are circuits between the input and the output that consume energy, sometimes they are called "active" multiples. Thanks to this, what is happening at the exit does not affect what is happening at the entrance, and consequently, the other copies of the entrance are also left alone.
