There are six pins on the Arduino Uno (shown below A0 ~ A5) that can be selected for an ADC measurement; A multiplexor feeds one of the six analogue input pins into the ADC. Thanks to the lively and helpful community surrounding the Arduino Uno, no one will find themselves without support. I hope that you already go through our first tutorial, Getting Started with Arduino Uno - LED Blinking.
