in series with a current limiting resistor). 7-segment displays are connected to the microcontroller in the same way as LEDs (i.e. Pin10 (g): This pin is used to control the middle LED of the displayħ Segment Displays which have 7 LEDs are arranged in a way that can display numbers from 0-9.Pin9 (f): This pin controls the top left LED of the display.Pin8 (Com): This pin is connected to Vcc/GND based on display type.Pin7 (a): This pin is used to control the topmost LED of the display.Pin6 (b): This pin controls the top right LED of the display.Pin5 (DP): This pin controls the decimal point LED of the display.Pin4 (c): This pin controls the right bottom LED of the display.Pin3 (Com): This pin is used to connect to Vcc or Ground-based on display type.Pin2 (d): This pin is used to control the bottom-most LED of the display.Pin1 (e): This pin is used to control the left bottom LED of the display.
