Hello,

I can not write and read 24c32 IC with my Arduino NANO 328. Can any help me please?

Hello,

Do you have external pull up resistors on the I2C clock and data connections?

No, I have not. What resistance is need to put resistors there?

4K7 or 10K should work if you have them.

You might also be able to use the internal pull up resistors on the arduino pins by writing a 1 to the corresponding bits of the port register using a C icon.

I have about million of resistors. I am radioamateur in past. But now I like to play with MCU
