Some friends of mine have started using LEDs connected directly to the track. (With proper resistors, of course).
This works OK, except for the flickering due to dirty track, etc.
I have several capacitors left over from an old project, so I would like to use these to smooth out the flickers.
Following are the questions I have:
1. With an LED in the circuit, do I need a diode? I am told that the LED is a diode, so another one is not needed.
2. If I add a Cap, is it inline with the LED or across the leads? (Serial or parallel)
3. What polarity?
4. What size Caps do I need?
Just starting to plan for this, so any information is welcome. (Like, what questions did I miss?)
