Why is there ≈4v on the control (forgot what it's called) pin (green), and why isn't the full voltage going through (purple) to the current limiting resistor (≈4v)?

4.2V on the base is normal since the emitter to base junction drops around 0.6-0.8V like a diode, the reason why there isn't 5V on the collector is due to emitter-collector saturation, the closest you can get is typically within 0.2V.

Thank you. That really helps. I'm going to use it more often in some of my circuits (in real life), so I needed to know.
