How do I connect a relay to the ULN2002A?
Connect the relay coil between the supply and the output pin, drive the input from the microcontroller, and connect the COM pin to the coil supply voltage so the built-in clamp diodes protect against inductive kickback.
Can it be driven from a 3.3 V microcontroller?
Its inputs are designed for TTL and CMOS levels, typically 5 V logic. A 3.3 V logic high may work, but check the input high threshold in the datasheet and test before relying on it.
