yesterday finally my Raspberry Pi arrived so that I want to start playing around with it immediately My first project (that seems a reachable goal) for me is to build a WIFI based illumination controller. While I am quite sure about the software-part, the hardware is (due to my lack of electrical engineering knowledge) a bit of a mistery
My original plan was to install an additional DAC (http://learn.adafruit.com/mcp4725-12-bi ... it-library) and connect the DAC to a Relais (http://www.conrad.ch/ce/de/product/5039 ... Detail=005) to switch a lamp on/off.
Now I wonder if there are better/simpler solutions? Especially, I am looking for a multi-channel solution (multiple lamps). How would one do a dimmer switch?
I am grateful for any kind of input! Best wishes from sunny Zurich,
