Hi,
I would like to design relay timer circuit using 555 timer and 12V relay. I want my design to be in such criteria:
Requirement:
First I will set the timer (for exampe 10s). Then I turn on power (supply the 12V). After 10s, the relay will switch from (NC) to (NO) and stay in such a way. The relay will only switch back to NC when I turn off the power.
Anyone got any idea how to design this circuit. Can it be achieved using 555 timer or need other IC? Please advice.
Thanx.
Nick
