/diy/ - Do It Yourself

Is the 5V signal referenced to 5V or GND? Is it floating? Any idea how much current it can source or what its output impedance is? Pic related are the only two good ways to do it, and if your 2V signal isn't floating you can only choose one or the other. If it's already referenced to ground you'll have to use an NPN instead.
Or use a dual inverter with complementary pairs like the other anons were saying I guess. What is that, like a switching sziklai pair or something? The doubling gain from the twin BJTs will definitely help if your signal source can't provide much help.
That or use a MOSFET.

Also 100Ω on the base is too low, use 1-10k or so instead. Consider the minimum hFE and plan accordingly.

Straying away from the walled garden of arduino is a fool's dream. First it's a PORTB.OUT, then you're buying a USBasp, then all of a sudden you're coding in vim. A rabbit hole leading only to darkness.
