Another cool electrical component‽ How exciting!

Transistors are used to amplify and/or switch electrical signals. This means that they can either increase an input voltage, or be used as electronic on-off switches.

The important thing to pay attention to when installing a transistor is that you solder each lead to the correct spot, because each one has a different purpose.

One is used as the current source.

One is used as a gate.

One is used as a current output.
