Reply to "LED Resistor heat:"

Since you already have a bunch of 470 Ohm resistors, you could connect 2 of them in Series to equal 940 Ohms. That's only slightly more current running through the diode compared to a single 1K Ohm resistor and well within the LED's specification.

Also the heat generated by each resistor would be roughly half of a single 1K. If they are physically separated by a bit of space these two daisy chained resistors would spread the heat more.
