i am looking for a circuit which has the follwing oparation:
when i give voltage to this circuit (12 v dc), after a time (approximately 40sec-1min) this circuit
to give 12 volts dc to a relay (12v dc/ 230 volts). i want this time to be variable with a variable resistor.
the circuit i am looking for is a power-on delay circuit.
i have listen many ideas like cd4060, CD4541 lm555 but i have not a circuit. please help me and post a circuit here.
thanks
