Arduino Data switching

Using Arduino Project Guidance
1

Hi

I want to be able to use the arduinos internal EEPROM but I also have to use the RX TX pins. The EEPROM has to read at the start of the code and sometimes used in the loop. Is there a component that can switch (disconnect) the RX and TX pins from the arduino, I could use relays but there expensive and big. Can transistors or some another component be used?

Thanks

Ian

The EEPROM does not depend on the Rx Tx pins for access.

What do you mean it doesn't work ?

Post code from read and write your using..
