  • Once more for the slow ones…me, apparently

    Question about this shield - I am attempting to get an analog signal from a flex sensor (SEN-08606) to the arduino through the analog inputs on the shield following the wiring guide at https://learn.sparkfun.com/tutorials/flex-sensor-hookup-guide. The circuit works fine on the arduino without the shield, but with it my range is extemely limited:

    Resistor / range arduino /range shield + arduino

    0.1 K / 15-70 / 536-545

    4.7 K / 50-264 / 844-853

    10 K / 140-430 / no range

    47 K / 400-800 / 1001-1004

    100 K / 590-903 / 1012-1014

    I am trying to position servos using the range, so I am severely limited by the readings that come across with the shield. It appears there is something about the analog inputs on the shield that impact circuit resistance significantly - is there a way to overcome this?

    Thank you Brian
