write and read values are different between two nanos via I2C

-

there pot connected slave nano. , want read master nano. when check serial port screen see master , slave nanos have different values pot signal. use 2 4.7k pull resistors comm wirings between a4 , a5. if send static value or char there no problem. when integer variable both slave , master have different values same pot signal.

why have, on slave, 2 variables named potread, different scope?

why read pot 5 times, , throw away 4 of values?

doing serial.print()s in isr (which istekgeldiginde() is) not idea.

why send 2 byte value, read 1 of bytes?

hi im working on 8x10 matrix leds , successful @ using guide http://www.instructables.com/id/810-led-matrix-with-4017/ using 4017 , 74hc595 now want expand matrix 16x10. i connected , worked added 74hc595 control second 8x10. my problem want display text using both 8x10 im using code guide , modified think doesnt work code: [select] #define someshape    {b0100001001000010,b1110011101000010,b0100001001000010,b0000000001000010,b0001100001000010,b0001100001000010,b1000000101000010,b1000000101000010,b0100001001000010,b0011110001000010  }    #define all     {b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111,b1111111111111111  }                        #define someshape2   {b0100001001000010,b1110011101000010,b0100001001000010,b0000000001000010,b000110000100001...
