Common Cathode 10-Pin 1 Bit 7 Segment 0.56" Green LED Display .This Very easy to use 7-Segment LED Display can be used with the Arduino Uno To create various numbers and letters.

Part # FND530

Height 1.5 CM x Width 1.5CM Here is a link to the instructables website for easy instructions on how to use with the Arduino Uno: http://www.instructables.com/id/Seven-Segment-Display-Tutorial/

And here is the Arduino Code to get you started:

// Define the LED digit patters, from 0 - 9

// Note that these patterns are for common cathode displays

// For common anode displays, change the 1's to 0's and 0's to 1's

// 1 = LED on, 0 = LED off, in this order:

// Arduino pin: 2,3,4,5,6,7,8 byte seven_seg_digits[10][7] = { { 1,1,1,1,1,1,0 },

// = 0 { 0,1,1,0,0,0,0 },

// = 1 { 1,1,0,1,1,0,1 },

// = 2 { 1,1,1,1,0,0,1 },

// = 3 { 0,1,1,0,0,1,1 },

// = 4 { 1,0,1,1,0,1,1 },

// = 5 { 1,0,1,1,1,1,1 },

// = 6 { 1,1,1,0,0,0,0 },

// = 7 { 1,1,1,1,1,1,1 },

// = 8 { 1,1,1,0,0,1,1 }

// = 9 };
