My end goal is to read information from an nRF24l01 module connected to my Arduino UNO R3, and generate an interrupt whenever a message is sent to the Arduino.
Now, I have read that for Hardware interrupts, only pins D2 and D3 can be used to generate interrupts. However, while connecting the MISO line, I saw that here it was mentioned that
On some Arduino boards (see table above), pins MOSI, MISO and SCK are the same pins as digital pin 11, 12 and 13, respectively. That is why many tutorials instruct you to hook up the target to these pins.
On every website I have searched, MISO is always connected to 12. Is there any way to change the MISO line from 12 to 3, or will I have to resort to using Pin change interrupts? Another way I can think of to bypass this is to connect D12 to D3, but I'm afraid this may cause complications in the circuit.
