I've trying make a very simple 3 LED circuit with a red, blue and green LED.
I know my 3v battery will take the path of least resistance and only flow through the red, so I've added resisters to the green and red at 47 and 56ohms respectively, as instructed by this website:
I also added a 47 to the blue just to try and help it, because you see the blue is still barely lighting.
I don't know what I can do beyond trying to balance their resistances which I thought I had now done properly.
Thanks in advance for the help.
