A Talking Sensor - Si7021 and Little Buddy Talker
Got to make one of these. I already have a little arduino project with an IR range sensor that sends WIndow L and hence locks the computer when I walk away. Regarding the issue with wandering paper, I wondered if something could be done with a paper laminator
Arduino Based USB Paper Gesture Mouse
Very nicely built. I have plans for something similar for a set of curtains. One thing you (or others) might consider if you ever do a revision is adding a temperature sensor. I have rooms where closing the blinds in the summer sun , and opening them for the winter sun, makes a huge difference to the usability of the room. Not so good for your plants obviously . Thanks for the write up.
Motorized Window Blinds Controller
Probably doesn't put 20mA through the LED with the suggested resistor. Look at the typical forward voltage drop of LED's (wikipedia says 1.8 to 3.3 volts). Much higher than a typical 0.8v for a small signal/regualtor diode.
