SCK on Arduino Mini Pro

Projects Networking, Protocols, and Devices

I hope this is the right section for my question. The Arduino Mini Pro has a LED and 330Ohm resistor connected to pin 13. Pin 13 is also used as SPI SCK. When using SPI do I have to disconnect the LED/resistor or would SCK work with the LED/resistor connected?

Thanks

No, you do not have to disconnect (unsolder) the LED or resistor. Most boards have them, and SPI works just fine.
