    Read correctly with AREF 2.5V J2. Arduino Kit

      Hi!

       

      I have changed the position of the jump 8 (AREF) to be able to read lower voltage (2.5V/1024 = 2.44mV and not 5V/1024 = 4.88mV) but when I do an analogRead, it read all time the maximum 1024. I don't know why. I tried to change to the j9 ioref, but I've not benn successful.

       

      Any recommendation?

      Thanks
