Step 6 Connect the 3rd pin (common) of the 7-segment display to the red probe.

Step 7 If a single LED glows on the 7-segment display, it is a common anode 7-segment display,
and we need to make the connections accordingly.

Step 8 If no LED glows on the 7-segment display, exchange the red and black probes. Now, connect
the black probe to pin 3 (common) and the red probe to the 1st pin of the 7-segment display.

Step 9 If the LED glows on the 7-segment display, it is a common cathode 7-segment display, and
we need to make the connections as per the common cathode 7-segment display.
