I bought the following MX035 7-segment display but I am very new to electronics and don't know how to wire it up. I soldered wires to each of the areas of the anode section of the board (A)....specifically defagbcpv
I thought I would be able to test the soldering by hooking the + from a 12V power supply to the "v" pin and then complete the circuit by hooking the gnd from the 12v ps to one of the other pins (e.g., "c"). My expectation was that the lower right segment would light up.
But nothing happens.
What am I doing wrong? Is the "v" pin not the common anode pin? and if not, what is?
I feel really stupid, so appreciate the assistance.
