Hi all,
continuing from my previous posts let me give an explanation of what I want to do.
I already have built a circuit that gives me an interrupt on a 12V input for 2 minutes through a 555 timer and a relay, as well as a 2 minute delay based upon a CMOS 4000 series and a selection of resistors and capacitors. What I wan to do is to trigger this circuit with a threshold of 1A. If current Is lower than 1A to have an output of 12V or 11V otherwise when current is higher than 1A to have an output of 0V.
The purpose of this circuit is to build a circuit that will detect is a pc box is on or off. When the box is off I want to cut-off the voltage supply(current 1A or less) for 1 minute and then give it back to the circuit, otherwise the circuit should stay neutral for.
