The main functionality of this unusual switch is to create a night lamp of sorts which goes into action as soon as the window blinds are closed.
The method is simple: create a simple circuit and attach two pieces of aluminium foil on both ends of wire where the switch would normally go. Attach foil on the window blind. When the blinds go down – the circuit is completed.
Although there is little functionality, the design is really flimsy and it looks very unappealing. This is my first time working with Arduino and I am enjoying it so far.
