Step 3Normal multiplexed displays
The displays I'm using here is of the Common Anode -type. That means that all the segments have a common positive pin. In order to light one segment you connect the common pin to plus and one or more of the segment pin(s) to minus.
A normal multiplexed display have all A-segments connected together in one line, and then all B-segments and so on. The common pins are then connected individually to the microprocessor. This makes eight lines for the segments and one line for the anode on each individual display.
