Hello everyone, this is a first post so I will apologise in advance if I have framed it incorrectly.
I wish to create a short 12v pulse [adjustable would be nice] my guess being around 0.5 seconds in duration. The pulse would need to be triggered when the input to my circuit becomes a constant 12v, or when it ceases to be [ie becomes 0v].
I had an idea of a relay using a capacitor and resistor to form a delay, but this would only work in the 12v constantly on scenario. Plus if possible I'd like to avoid relays if possible and anything that creates a sizable drain on idle.
Any ideas would be welcome.
