I'm a hobbyist and pretty new to many of the components involved, so I hope you guys can help me here. I'm trying to keep the circuit as simple as possible.
I made a small variable power supply with a buck converter and would like an LED to come on when my output reaches 5V. I'm not really concerned about it staying on after 5V is exceeded, but I definitely want it off if the voltage is lower than that. After looking into it a bit, I'm assuming I'll need a MOSFET or a transistor of some sort but I don't know enough about either of them to begin finding the correct one. If it matters, here is the buck converter I'm using:
The only other things in the circuit are a volt meter wired to the output and powered from Vin and GND and I replaced the potentiometer with a larger one.
