Hi to all and happy new year!!!
I'm studying the circuit in figure below
and i don't understand how it's work, from a theoretical point of view, when the uC pin is 1 or 0.
I've made some simulations and i've noticed that the square wave on the output is amplified when the pin is at high logic level, so +15V on R1. That's true?
Could you give me some help in understanding? Thanks
