Hi all ,
I have been building many projects where I face a common problem while using a 555 delay circuit. The thing that I have noticed is that every time I switch the circuit off and switch it on again I get a different time delay than expected I.e I get the time delay as per calculations only for the first time . So in order to do that , I had a reset switch which I used to control a relay to short the + end of the capacitor to ground via a 10 ohm resistor. As it thought this might be a crude way of doing this, Is there any other way I can get this stored charge to back to zero?
Thanks in advance.
