These are the slides for my 'How to make a night lamp out of a beer bottle' talk we had in the TinkerSoc OpenMic #1 (http://bit.ly/4uo3uC) It mostly covers different ways to detect 'touch', using capacitive touch sensing solutions and how to make a simple on-off controller using a flip-flop. Comments/Suggestions to: omer@tinkersoc.org please...

Editor's Notes
- The memory elements in a sequential circuit are called flip-flops. A flip-flop circuit has two outputs, one for the normal value and one for the complement value of the stored bit. Binary information can enter a flip-flop in a variety of ways and gives rise to different types of flip-flops.
