Wedding is a special occasion. This is where two meet and swear love for the rest of their life. Sometimes happens that both are geeks. And here fun becomes. Billy and Mara decided to make the wedding memorable by turning it in to geeky event. First step of course is invitations.  Instead of posting simple invitations they decided to put a circuit inside which would remind guests how it’s going to be.

As you can see invitation card already is a circuit styled, but most fun starts with real circuit in it. They added a tiny AVR microcontroller which drives four LEDs. There is also light sensor to detect if there is dark enough to start light show. Seeing the invitations I can imagine the wedding itself. Congrats.
