What is the pinout of the BD137?
The standard BD137 TO-126 pinout is Emitter (pin 1), Collector (pin 2, also connected to the metal tab) and Base (pin 3). Pin order can vary by manufacturer, so confirm it against the datasheet of your batch.
How do I drive a relay from an Arduino pin using this transistor?
Use a base resistor between the Arduino pin and the base, connect the emitter to GND and the relay between the collector and the supply. Add a flyback diode across the relay coil to protect the transistor from voltage spikes.
