I have brought this board recently and trying to use this board for testing a 5 button key press using voltage diff.
My volts when measured in multimeter are Button 1 - 0.2V Button 2 - 0.4V Button 3 - 0.6V Button 4 - 0.8V Button 5 - 1.0V
I have tested this board in Seeeduino_Mega and its working fine
But when I connect the same to arduino due board i am reading
Button 1 - 0.3V Button 2 - 0.6V Button 3 - 0.9V Button 4 - 1.0V Button 5 -5.0V
Please suggest what could be the issue.
