Hello,
I am wanting to include a timer circuit camera modification I am making. This will be the first time I have used the 555 IC so be easy on me with the below questions.
All I am wanting to do is delay a relay from closing by triggering the IC to send a single pulse to a NO relay instead of the current direct connection which closes it and complete another circuit immediately. In looking at the pins of the IC, I have read that pin 2 is the trigger, pin 3 is output and pin 4 is the reset.
Does a voltage coming down the line cause the trigger to set or what makes the function of the IC begin?
Am I required to do anything with the other pins since I am only wanting to cause a delay with this IC?
Can I wire the output(pin 3) to the reset (pin 4) so that the output voltage makes the IC reset?
Any suggestions here?
