I’m completely new at this and need help to design simple low 3-6 voltage OFF-delay timer.
Here is what I need:
1.Power supply would be 3-6volts
2.Timer should not have any buttons and switches, once power applied to the circuit it should activate relay for about 3-5 second and then release relay contacts by cutting off power from relay (time not very critical and can vary plus minus few seconds)
I know it can be accomplished by using single transistor and few capacitors & resistors but I’m never done it on my own plus I’m unable to find something similar on internet. I’ll be appreciated if someone can help or point to right direction.
