    Hi all, I'm trying to learn electronics and have built this simple circuit with a PUT. While I think I understand the logic of this, I am confused about a few things and wonder if anyone could shed some light.

    - How were the 15K and 27K resistor values were chosen?
    - How do I calculate what the voltage threshold is at the base of the PUT?

    Any help is very much appreciated!
