Hi everyone,
I need some help with a fairly simple circuit, that is supposed to activate a relay a few seconds after power is applied to the entire circuit. The delay should be controllable through the potentiometer.
Now my questions: Are the values for both the potentiometer and the capacitor appropriate for a darlington pair? I was thinking of using a pair of 2N3904 - would these work?
Am I right in thinking that the relay should open again, immediately when power is removed from the circuit?
Thanks for any help!! Odysseas
