I'll start with an apology. I sneaked into this forum as I find it interesting. (I'm a mechanical design guy and electronics has always eluded me lol)
I'm sorting a little project where I'm making a water depth indicator with a float, magnet and linear array of reed switches. The indicator panel uses a number of individually addressed 5mm leds. It's vehicle based so 12v. The leds don't need to be madly bright or anything but I have no idea what value resistor to put in. Any suggestions would be much appreciated.
Thanks,
Les
