Intro: 7 Segment Hack
Hey, This can be a fun project for the weekend.
You can hack it to your own messages too...
This step to step guide can help you make it quickly.
It requires only 4 parts and the project is complete within other few steps
Step 1: Join the 7 Segment and Probe Wires to the Bread Board.
This image is self explanatory. You can make these connections by placing the 7 segment right in the middle of the board so that the ravine which flows between the board helps you to distinct connections with the 6 pins on both sides of the display.
Step 2: Make Connections With Your Arduino Now.
Connect 2,3,4,5th pins of UNO to the pinout of the display as COM1, COM2, COM3, COM4.
Also connect the remaining 6 to 13th pins of the UNO to the A,B,...,G and dp(data pointer) of the pinout of the display.
The pinout is in the next image.
Step 3: LOGIC
This logic will help to decipher any circuit like the name printed on it. Like i have used CA display.
More explanation is shown of the logic in the image.
Step 4: The Final Code and Output.
You need to put these files in one folder. The 7_segment.ino is the code file while segmentchar.h is the library file.
