Hello, could anyone tell me what and how I achieve this:
I have a usb LED, it's built with a cut off usb cable, a 180ohm resistor and the LED. Anyway, since I don't want it to be on all the time I want to add an additional function. When the lamp isn't shining, you flip a switch or a button and the LED starts to shine for a certain amount of time (let's say one minute for example).
Sooo, how would I achieve this?
Thanks!
