Let there be light! (Update)

Following on from the previous post I have a correction to make. The 270 ohm resistors that shipped with the LEDs aren’t overkill for the 3.3V Raspberry Pi GPIO circuit. There must have been a mistake in the way I built the original circuit, since when re-trying it the other night, it worked perfectly fine (albeit slightly dimmer than intended).
