I write a monthly column in a dutch newspaper (De Volkskrant) in which I show people builds of stuff that they can do at home. For this months instalment, which prints tomorrow, august 30th 2014, I used a spark core to switch on or off a lamp at my home. I made this lamp-switch available on my website, so anyone can turn on, or off, my lamp. I added a webcamfeed to my site and an LCD to my spark so people can see that they are actually controlling my lamp.
all code, both for the core as for my website is posted in this repo:
Hope someone can (re-)use part of this!
