+ | [* black] Another cool electrical component? How exciting! |
[* black] 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. | |
[* black] 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. | |
[* red] One is used as the current source. | |
[* orange] One is used as a gate. | |
[* yellow] One is used as a current output. |
