Hi all, this is my first electronics project and I need a bit of help getting started.
I'm looking to make a very simple vibration activated LED and cr2032 battery combo light to illuminate the water tank in my espresso machine.
So far I plan on using a normal white 5mm led as well as this vibration switch. I understand that the simplest circuit would be to use just the battery, vibration switch and the led. This would light the led while the switch was vibrating. BUT, if it's not too complicated I'd like to have the LED stay on for a while... maybe 30 seconds or so? My extremely limited electronics knowledges suggests that a capacitor might help with this but I have no idea what the circuit would look like and I haven't been able to find anything similar online.
One last thing, I'd like the battery to last for as long as possible, the LED won't be on much other than when I'm using the machine so it should be able to last a very long time (I think). Also, the overall size is a bit on an issue as, ideally, this would all fit in the (dry) space underneath the water tank. That space is about 1"x1"x.5".
So, any chance that one of you electronics gurus could suggest a simple circuit to keep the LED on for a while? Any help is really appreciated!
Thanks!!
