Hello,

I would like to add a switch of starting stop;
diagram attached.
Is this ok?
Does one need meter a resistor before the led? so yes which value?
thank you.

I'm not sure it'll work since the LED wil add quite noticeable voltage drop. But you can try it since there is no harm in doing this:)

Ok for the switch, but not for the led.
You can not add a led like that (0.7v drop).
The LCD backlight is not enough ?

You can do that :
