My backpack is very long and very dark inside so al my stuff is lost in there (including a banana for 2 weeks), so I would like to build a LED (or 2) in it which would turn on when I open the top.
I was thinking of using a circuit in which the switch and led would be placed in parallel. When the switch is pressed, the led would be connected directly to ground and would turn off.
But, this circuit would draw current continuously and would drain the battery quite quickly.
Is there a better way?
