Step 1: CONNECTIONS

1) FOR A COMMON CATHODE 7-SEGMENT LED DISPLAY:

"A" -> DP 3

"B" -> DP 2

"C" -> DP 7

"D" -> DP 8

"E" -> DP 9

"F" -> DP 4

"G" -> DP 5

"H" -> DP 6

COM -> GND

2) FOR A COMMON ANODE 7-SEGMENT LED DISPLAY:

"A" -> DP 3

"B" -> DP 2

"C" -> DP 7

"D" -> DP 8

"E" -> DP 9

"F" -> DP 4

"G" -> DP 5

"H" -> DP 6

COM -> VCC

Step 2: PROGRAMMING

1) Download the code based on your version of the display.

2) Verify the same.

3) Select the right communication port and board.

4) Upload the code.

Step 3: TESTING
