teeny tiny circuit to make led fade in and out. Answered
good morning. long time lurker, first time poster. i am working on a small project and thought this would be the best place to ask.
i need to come up with a teeny tiny circuit that when power is applied will fade in an led (over 1sec), and then when power is removed will fade back out (1sec). it doesnt have to be exactly 1 sec, but somewhere in that ballpark.
the space i have to work with is only 21.91mm X 6.02mm X 19.4mm, and id like to also be able to add a small switch in there too so i can disable the led when its not needed.
input voltage is 12v and i need 5.5v out, 6v max.
any ideas are welcome. i have found a few circuits on here already, but most are way to big to fit into the tiny space i have to work with.
