Dear all,
I am using Arduino uno in my project.I want to interface rf module,sd player module on the same arduino(according to my application).but both liabrary of this modules shows almost same pins as i studied about there interfacing.Then how to use this module simultaneusly on the same arduino.Can i change pin configuration of module??please Reply.I am using following modules with arduino.

Hi,

You want us to guess what arduino hardware you use, which pin you are talking and what code you use?
You want us to guess what modules from what vendors your pictures show, find the according datasheets and read them for you?

The modules use the SPI bus to communicate with the Arduino. SPI uses a chip select pin to enable the SPI slave device. Arduino can have 2 slaves on the SPI bus. Here is a link to an example nRF24L01 module implementation:

https://lastminuteengineers.com/nrf24l01-arduino-wireless-communication/

In the example sketch above, it looks like pins 8 and 9 are being used as enable pins. The SD card module should be able to use pin 10 as its enable on the same bus. It will also be necessary to make sure the sck clock frequency is correct for the module being communicated with, and insure that voltage levels on the SPI bus are compatible for both modules.
