Hello, I need a circuit that I can put together with regular I.C. I don`t want to go to the PIC route yet as I am not reading for that learning curve yet and this is a very small production run, 1- 4 boards.
I am into R.C submarines and I need a circuit that when it detects that the transmitter signal, 75mHz FM is missing, then the circuits turns on and runs for a user set time, a small D.C. pump, 1 Amp max.
The set run time is done by a variable pot by the user from on instantly from detection of No signal to 30 sec. max. ( 0n instantly - 30sec. run max. )
The only way to reset the system would be to turn on/off the main power by the operator. The main battery is 6v - 12v max.
If there is No loss of signal then the circuit lets the signal pass through to allow normal use of submarine. So it would go between receiver and pump motor, the pump motor should also be able to run on command of operator.
I hope someone can show me a working circuit with all the parts listed so that I could put one together and try it out.
Thanks In Advance for your help.
