A seven segment display is composed of seven elements that individually on or off can be combined to produce simplified representations of the numbers 0-9. There are two types of 7-segment displays: Common Anode with all the LED anodes connected together.
A Common Anode Green 7 Segment Display, 14.2mm high. Incorporates high efficiency, high brightness LEDs with a high contrast between digits and background.
The seven segments LED display is store in the SSEG() constant array, therefore by assigning this array to the PIC16F886 microcontroller’s PORT C (RC0 to RC7), the corresponding LED’s segment on the seven segments display will be pulled to the ground (low), and by pulling low the corresponding PNP transistor (T1 to T4) base lead attached to the PORT B, we could make the seven segment to.
A Common Cathode Green 7 Segment Display, 14.2mm high. Incorporates high efficiency, high brightness LEDs with a high contrast between digits and background.
This tutorial assumes you are somewhat familiar with 7 Segment LED Displays and builds upon the 7 Segment LED Displays 101 -- How to Make One Work tutorial. To complete this tutorial, you will need the pinout for the 7 Segment LED Display you are using. If you do not have this information, please see the previous tutorial.
Im going to be using a 7 seg display in an upcoming project, so I thought it was time it was added to gpiozero, can I get some comments on my thinking so far: class name of 7SegmentDisplay extending LEDCollection overwriting value to tak.
