Hi everyone,
New here and I have done some basic electronics but 15 years ago now and I just cannot remember much! I am trying to design a circuit (quite urgent as I should have done it 2 weeks ago now!) which does the following:
Toggle switch on which then sets a 45 or 60 second timer (it would be cool if I could have a display timer if it's simple but not important. I would like a sound output too (beeping as loud as I can get) for this during the timing.
I would like flashing LEDs in red x3 during the timing too.
Now here is the part that's important. I would like a separate push to hold for 5 second switch which will switch the timer off. I also want it so that the toggle switch CANNOT switch off the timer. Only the push to hold.
I would like an indicator that shows unsuccessful switch off by push to hold or timer up too.
I know I'm asking a lot by saying can someone design this for me, but I have just forgotten completely. I would be grateful.
I can implement it though here is another question, how do you do the printed circuit board at home? I mean printing the tracks etc, not putting the components on
. I don't have the facilities but can probably get certain things if not too expensive to print the circuit board.
Appreciate the help
