What I've tried to do is create some simple led circuits with as few components as possible.
These can all be built fairly easily on a breadboard or with some alligator clip jumpers.
((((I'm sure that mistakes were made, if so, please comment and I will correct them!!!!!))))
First, all leds are set at 2v and 20ma. These settings can be changed by selecting the led then the wrench icon. In real life leds have different voltage and current depending on size color application etc...
-----------'-----------'
1st Top - Led On/Off
Led with 350ohm current limiting resistor
Close SPST / Open SPST
------------
2nd Top - Led On/Off
Added one NPN transistor and
One resistor for led protection
Close SPST / Open SPST
------------
3rd Top - Led On/Fade Off
Added one capacitor
Close SPST / Open SPST to begin fade
-----------
4th Top - Led Off/Delay On
Added one resistor
Close SPST / Wait for fade on / Open SPST
----------
Bottom Left - Led Off/Fade On
Removed one resistor
Added one NPN transistor
and one capacitor
Close SPST / Wait for fade on / Open SPST
-----------
Bottom Right - Latch
Removed one capacitor
Added one relay
and one resistor
Close SPST
Press left NO switch to Stop
Press right NO switch to start
Open SPST
