I have just started with arduino so i dont know alot.Im a trying to create a connection with objects for a project. I'm trying to detect the movement of a candle flame and sync a light bulb with it so the light bulb flickers. i would be very grateful if someone could advise me on a good sensor and the way to go about creating this connection between the two objects.
Instead of printing the values you can put the values in a function that approximates the flickering. The output of that function is send with digitalWrite to a PWM port control a LED light. You can find this on the reference pages and tutorial sections of arduino.cc
You can also map every LDR onto its own LED, program a memory effect and add additional random fluctuations but that is for version 2.0. First get started with 0.1 understanding teh sensors and the basic program.
Thanks, instead of a LED, i would like it to be a household lightbulb but i know the voltage output would not light an average household bulb and i would need another power source and i have researched arduino boards and i am thinking arduino uno would be best for me especially as i am just starting off but i want to be 100% sure.
yes
an Arduino UNO has 6 analog ports so you can even do 6.
YOu can combine these values into one value between 0-255 and use this to analogWRite() a PWM signal which is used to drive teh lightbulb.
But the latter you should ask on the electronic subforum: - how to drive a 220V bulb with PWM.
[mind you I don't know the formula of combining the 4/6 inputs to one output. Averaging does not seem like a good idea, as you want both the peaks and teh minima and duration and ...
If you find the formula please post
