In the data sheet you will see a schematic showing the output is on connector CN1. This is a 10 way connector the first two pins are ground and should be connected to the arduino's ground. The following 8 are the data pins giving the binary value of the number displayed on the seven segment displays in a BCD ( binary coded decimal ) format. Simply connect these to 8 arduino input pins. Reading these pins will read what number is being shown.
