For NPN transistors (and PNP) always use resistor between base pin and MCU pin (or other) because otherwise MCU will sink as much as it can from base to emitter and blow it's brains out.

Using NPN on high side also has some other issues but a bit too technical for now (if you want NPN on high side - use optotransistor)
And recommend avoiding PNP transistors for time being until you learn more
