i want to be able to monitor and controll lights in my room to prevent wasting electricity
i have 3 LDRs (one for indoor light, one for outdoor and 1 for ambiant light)
And a PIR to detect if someone is in the room
i also have arduino board and bread bord
i need to take in readings form LDRs and PIR and combine them to make a decision as to weather or not turn lights on or off. And i want to store what iv been monitoring so i can see what im saving/wasting
for the moment im not too pushed abot the controlling, if the lights should be on i want to light a green LED if not i want to light a red LED
powering the hold thing will be a problem, im thinking DC power supply??
The mjor thing thought at the moment is making a decision using all the sensors, iv a list of conditions and am working on what is optimal light for a room, but how do i use all the readings to make a decision.
please help, im abit of a n00b!!
