Sorry for not providing enough details. I'm making a halloween costume of an arc reactor (from iron man).
It should look something like this when its done:
I'm waiting for the chrome paint to dry right now, and im planning out my circuit.
From the picture above, the clear parts will have an LED behind it (blue led, 24 mA, 3V, 8000mcd to be exact). I bought my first Arduino UNO and wanted to use it to make my LEDs (10 LEDs in the center making a ring), fade on, and 3 LEDs in the very center. I wanted to be able to use a button I bought to switch modes (One mode dim, one mode bright, one mode pulses, and one mode makes a train of lights).
I have a 4 AA battery pack that should supply 6V (1.5+1.5+1.5+1.5), and I bought a vaiety pack of resistors from Radio Shack as well as a Bread board.
What I thought: Battery->Arduino->Resistor->Breadboard->LED->Ground.
My main problem now is calculating which resistors to use (the wizard tells me the same resistor no matter what mA I put for the LED) and where to put the LEDs (1 LED per resitor, or 2 LED per resistor!! so I can use the 6 PWM (12 LEDs total) (so that it can fade and do the cool stuff).
Should I draw a diagram to help show what I want to do or is that good enough? Im willing to provide whatever necessary to make my Halloween project successful!!
Thanks again! I have a good feeling about this! :D The Resin Parts look pretty cool :P
does that help give a better picture?
