    Please note that the AREF pin needs to be connected to the 5 volts power supply to use the Analog pins. This is not done by default on TheUno V2.0. Connecting the AREF pin to the 5 volts power supply on TheUno V2.0 can be done using a simple wire fixed on the PCB. It is also possible to connect the AREF pin to the 5 volts power supply on one of the shield.
