View source for Always-on circuit guide

This circuit will check a device - in this example a [[Wall Light]] - and restart it, if it will shut down / deactivate for a reason.

== Trivia==
*This little thing was invented by user '''"Simoyd"''' in discord-chat "logic-ciruit-discussion" and needed and created by user "Raumfahrtdoc"
*This is super useful to restart the [[Kit (Gas Generator)]] / [[Gas Generator]]

== Improved version ==

[[File:Improved Always-On-Circuit.png|thumb|Improved Always-On-Circuit using only two I/O and two processing units.|thumb]]

Using the new [[Kit_(Logic_Processor)#Min.2FMax_Unit|Min/Max Unit]] as an OR gate and [[Kit_(Logic_Processor)#Compare_Unit|Compare unit]] as a (controlled) NOT gate, a much cheaper version is possible. Basically, it is a controlled clock that only runs when the device is off and otherwise stays at 1. The circuit can also be modified easily to make an always-off circuit (e.g. to auto-close doors), see table below.
