My original idea was to put a light which color automatically changes over the time behind the bed, but the project has evolved to a more useful gadget. Now RGBed has these features:
Controlled by an Android app via Bluetooth.
8 light modes, two of which uses the mobile's microphone to create an audio spectrum effects.
The temperature color changes depending on current time.
An alarm for each day of the week to power on of the light at some hour. [Under development.]
Connections
The LED strip is connected to the pin 10 following the instructions from Adafuit. The DS1302 RTC module needs 3 pins, CLK, DAT and RST, wich are connected to the pins 11, 12 and 13. Finally the HC-06 Bluetooth module are connected to the RX and TX serial pins. I used a perfboard to connect all modules, with some connectors to make easier to replace/remove anything.
Case
I designed a little case with Sketchup. Some parts are to fragile and need to be improved, but it works.
App
The Android app allows to select the mode and colors easily. Also can synchronize the RTC with the mobile's clock and set/unset the alarms.
