Nov 16, 2015 · Using the pin-numbers from Alex’s photo above (and assuming your 4-digit 7-segment displays are identical) you’d simply connect each of the LED-pins 1,2,3,4,5,7,10,11 together in parallel, and then the LED-pins 6,8,9,12 from each display would connect separately to different GPIO pins on the Pi (using 8 + 4 + 4 = 16 GPIOs in total).

Seven Segment Displays: A 7-segment display is a device made up of seven LEDs connected in parallel that can be used for displaying numerals and some letters. Different letters/numbers can be represented by connecting different pins on the display to the power source, thus turning on the LEDs in parallel. Mar 20, 2017 · 5611AH Datasheet - 7 Segments, LED Digit Display, 5611AH pdf, 5611AH pinout, 5611AH manual, 5611AH schematic, 5611AH data, 5611AH circuit. 7 Segment displays are fairly easy. You'll need 7 I/O pins for each digit if you do it without an additional components. Otherwise, pick up a shift register from Sparkfun. You can then drop the I/O requirements significantly. The datasheet shows that each of the seven segments on the display are labeled as a,b,c,d,e,f,g and dp (decimal point). The Serial 7-Segment Display turns the thirteen pins necessary to control a 4-digit 7-segment display into just one or three. The display will give you full control of all digits, decimal points, the colon and the apostrophe. At the heart of the display is an ATMega168 which controls all the serial communications and the 4-digit 7-segment display.
The 7-segment displays are really just seven LEDs lined up in a particular pattern. In this case, the number ‘8’ shape we’re all familiar with. Each of the seven LEDs is called a segment because when illuminated the segment forms part of a numerical digit (both Decimal and Hex) to be displayed.
