Also, the project isn't a remix - I was using this guy's design, and then I deleted it and started over, and I didn't change projects.

I'm trying to make a map with lighted pushbuttons as landmark markers

It only works with red LEDs

#

This raises an interesting question: Do red LEDs draw more current/voltage than blue/green/white LEDs??

#

I'll change the color, but I still want to know whether the red LED is the problem

#

These LEDs are just normal 5mm LEDs

The red and green LEDs do indeed pull more power than blue LEDs. My solution is to reduce the resistor to 220 ohms.

red - 500ma

green - 450ma

blue - 530ma

warm white - 630ma
