How to connect SPI if I am using pins 13,12,11,10

Projects General Guidance

I want to connect my NRF24 module to my uno but also I want to use the pins 13,12,11,10 (which I know a little are used for SPI ) for digital outputs to LEDs.
where do I connect my NRF24 to??

There is a Software based SPI library out there, but quite slow.

But you cannot re-direct the hardware SPI pins on a UNO.

Are the analog pins currently used ?

4

I am not using the analog pins, but can I use ICSP header on arduino board and use 9,8 for CE and CSN respectively?

5

You might want to check the pinout diagram of the UNO ?

The ICSP header used the pin 13,12,11 SPI connections ...............

6

You could use the analog pins as digital outputs to LEDs and free 13,12,11,10 pins.
