Troubleshooting advice for basic transistor + pro mini setup

wvmarle:
The current will never get bigger than what the transistor can pass through. That's how they're used as amplifier in radios etc - a very low resistance load and the transistor regulates the current.

In your case you have a base current of 1.7 mA, and based on the data sheet the transistor will be able to supply >200 mA (collector saturation until about 100 mA), the data sheet that I found is not too detailed about this.

Cool, so if I understand correctly the transistor will not get damaged, and a load that tries to pull too much current will see a corresponding voltage drop?

Sounds perfect, thanks!
