Hello all..
I have a simple LED monitor for a small heater/fuse circuit I've got but want to add some extra functionality that I'm not sure how to accomplish and could use your help.. My friend said this forum is great for that..
I'm hoping that some simple combination of transistors/capacitors/resistors can be used to keep it simple for me to build.
So..
In the attached circuit I want to be able to disable the red LED if needed..
Sometimes I want to remove the fuse or the fuse blows and the power supply stays on but I don't want to see the red LED and need a way to temporarily disable it..
I thought it would be neat if I could somehow insert the good fuse and if I removed it within 5 seconds or something the red LED wouldn't turn on.
If I put the fuse back in and left it for longer than some time period then it would function as normal and if the fuse blows I see the red LED again..
Can anyone show me how I could do that? thanks
