Is there an example for using a 10 pin 2 digit 7 segment display similar the picture below? It is common anode and actually has 10 pins (pin 2 is the DP or decimal point). See the full post on his blog. If we like to display the digit say “123” on three displays first we select disp-3 by applying a “low” level at the base of transistor Q1 and output the code of required digit at the data input terminals. The MAX7219 based 8 Digit 7 Segment Display module takes care of that, running all eight digits from just three IO pins. The remaining 8 pins are then responsible for lighting the segments a-g (and the dot - DP) on the display. The severn-segment display has seven LEDs arranged. It is costly in terms of electronics. The other 4 pins represent each of the 4 digits from D1-D4. 3" 7 segment display with rtc ds1307 2017-11-07 In this tutorial, you can learn how to make a digital clock using large 7 segments 2.
