Build A Music Playing, Curtain Opening Wakeup Machine
Build a musical curtain opening wakeup machine with littleBits. via instructables
A cloud-connected circuit that automatically opens up your curtains and plays a wake up sound every morning at sunrise (or other time of your choosing).
Using IFTTT we can send a trigger signal through the cloudBit at a scheduled time every day. This signal goes down both wires of the Split Module. On one end it causes the servo to pull the pin that is holding up a counterweight. When the pin is pulled, the weight falls, pulling the cord that opens the curtains. On the other end of the split, the trigger signal causes the mp3 players to start playing a sound file. This file is played through the speaker, which is hooked up to an old radio horn for amplification and general awesomeness.
