Hello everyone!
I'm New in this forum and new to arduino .
Iwant to build a project and I think that with arduino it will be perfect.
so I'll tell you about it and I hope that you will help me.the celling in my room and my bathroom is glued with leds, for now I activate the leds with rf remote control.
what I want to do is this:
1.when I open the door I want to turn led on for few seconds (the arduino should be connect to switch/momentary button).
2.when I open the bathroom door the leds turn on and stay on until I leave (switch and motion sensor).
3. The thing that trills me the most-control all of those lights by my smartphone!
So friends I would really appreciate your help.
just tell me what components I'll need and the basic idea of you.
Well, the first concern is that a door may or may not be open or closed when a person is in or out of the bathroom, so I wouldn't try triggering anything using the door. It seems like a PIR (passive infrared) sensor might be a good choice to determine if someone is actually in the bathroom, although a warm bathroom (like after a shower) might fool the sensor. Careful sensor placement could ameliorate this problem.
As for the smartphone, you could buy an internet shield for the Arduino, and then arrange to send an email to the Arduino from a smartphone, with the Arduino then acting on the contents of the email. I've started on a project like this, having bought the internet shield, but I've only gotten as far as knowing that it less than completely simple to process email with an Arduino.
If your phone has Bluetooth then that may be the quickest/easiest/cheapest control short of hitting buttons/etc with the phone instead of a finger.
Did you wake up after a big party to find your ceilings have leds glued on and are trying to figure out what to make of that? Usually we don't install the leds until after they are wired, after we know what we will be doing with them. You might wish that you had done that before long.
hi.
first of all the leds are currntly working!
i just want to improve whats trrigering it..
motion sensor for the bathroom and i think that a clap switch + door switch would be great (when ill open the dor the lights will turn on untill i clap my hands.(possible with arduino?))
if you have other ideas please share!
You could try a knock sensor which uses a piezo disk, aka acoustic instrument sound pickup. You could set up different knock patterns to do different things.
You could experiment with capacitive sensing. That can be from touch a spot to be feet away. I personally do like cap sense since you can do it cheaply and there's no moving parts. You could make parts of the door or walls into hidden switches.
You can get an ultrasonic sensor, some cameras use them to tell how far away the subject is.
Someone already wrote about PIR that sees body heat. What it senses is movement/change in IR.
There is also active IR where the subject reflects IR light back to sensor(s).
An microphone makes electrical pulses when sound hits it. There's a Youtube showing using an Arduino to trigger a fast camera when a balloon pops. The pictures show the balloon in the act.
