CR and Newbie thanks. I'm trying to build a working knowledge of electricity as I go along here. To your points:
-
So, to get the best voltage through the Arduino, I need to connect the DC power supply - 12v is the max (I think).
-
CR, the arrangement and functionality of my design would work much better if the LED's in each bank were wired in parallel. Radioshack has this LED, which I was thinking of using:
Peak emission wavelength: 660 nm
Light output: 5000 mcd @ 20mA
Forward voltage: 1.85V
Absolute maximum ratings:
Forward current (continuous): 30 mA
Forward voltage: 2.5V
Reverse voltage: 4V
Power dissipation: 75mW
If I wire in parallel, would each LED need a different size resistor depending on it's position in the bank? (that math would be beyond me!)
- I understand the concept of the Mouser Transitor, but not how to wire it with it's three pins. Obviously one goes to the Arduino port for it's respective bank, one goes into the individual bank it belongs to, but where does the other one go?
Again, my thanks. CR, how is the snow in Boston?
