Simple Circuits

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 
          ----------

Hi Wyoelk, This is great work. Could you add a latch in to one of these cct?

Yep, I've got 2 more "versions" coming maintaining the same basic list of components

hello you commented on my bridge rectifier i was wondering if you could add me on discord so we could further talk about this I would appreciate a lot V3rtig0#8897 or you can email me at Skyyjaden20@gmail.com

Hi Wyoelk great examples of how it should be done! How have you been? it's been a long time mate , I know that's my doing 😏

I been dandy fine, and you? Aren't you living in the land o'plenty down under?

LoL no, ain't that the lyrics from Men at Work 😄 ? I'm in the land of old blighty (UK). I'm doing fine too. It's good to see some of the original crew are still around and pest free 😉

Yep, the joy of building and experimenting was almost gone. Just an FYI I'm from big old Wyoming
