Capacitive Touch Encoder

-

hey,

i looking add capacitive touch capability rotary encoder.  thinking of using adafruit mpr121 touch sensing.  using metal knob , rotary encoder metal shaft, there concern interfering function of encoder?

the change in capacitance of led's pn juntion when turned on , off can enough set off capacitance sensor if proper precautions not taken. believe actuation of encoder's switches problematic.

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...
