What is the pinout of the BC547?
With the flat side of the TO-92 case facing you and the pins pointing down, the standard order is collector, base, emitter from left to right. Verify against the datasheet of your manufacturer, as pin arrangement can vary between brands.
Do I need a resistor on the base when switching an LED?
Yes. Connect a resistor between the controlling pin and the base to limit base current, and keep the LED or load current under the 100 mA maximum. The value depends on the supply voltage and the required collector current.
