I plan to get the LK204-25PC lcd. Can I connect LEDs directly to the GPOs, or do I need to add a limiting resistor?

unless your leds are 12V, then you will need to use resisters.

I want to use 5v LEDs. What type/size resistors should I use?

Many Thanks.

You can use this calculator over at Bit-Tech:

If you supply it with the correct details, it'll tell you what value resistor you require.
