Can BC177 switch a relay directly?
Only very small relays, because the continuous collector current is limited to about 100 mA. For larger coils use a higher-current transistor or a MOSFET driver, and always add a flyback diode across the relay coil.
How do I wire BC177 as a switch with a microcontroller?
Connect the emitter to the positive supply, place the load between the collector and ground, and drive the base low through a base resistor from the microcontroller pin to turn the load on.
