I have a 5V supply to turn my circuit on, and i need a one pulse circuit. The condition should be look like this;
When the circuit energized with 5 V it should go low after t1 time and it should stay low for t2 time. Then it should be switched to high condition and stay like that. This cycle should go like this for one time when circuit energized. How could I achieve that condition for my circuit? Unfortunenatly I can't use any MCU for that.
Note: I'll control a 5 V relay with this circuit if it will make a difference.
Note2: I made a circuit with 555 timer in monostable mode but it needs a switch for the trigger pin. I can't use that because circuit must be automatically do that after energized.
I hope I explained my problem well. Thank you for your possible answers.
