Sup lads. I'm working on a little project for the place I live/work. We want to set up an automated irrigation system, for which I've purchased one of these: https://www.adafruit.com/product/997

It says I should wire it with a TIP120, which I don't have. Googling tho, it seems this is just a 'darlington pair'. i don't know much about electronics, but could I just construct a darlington pair (I have a bunch of transistors) rather than buying a TIP120? Any pitfalls with this approach? Here is the circuit diagram of what I am planning
