Resources and Going Further

Now that you're comfortable using one of the Serial 7-Segment Displays, it's time to incorporate it into your own project!

For even more information on the 7-segment displays, please check out the Serial 7-Segment's github repository. There you'll find:

  • Datasheet - A Wiki containing all of the information you should need to use the display.
  • Arduino Example Code galore - We went a little crazy with the test code. You'll find something useful here.
  • Firmware - If you're interested in modifying the behavior of the S7S, definitely check out the firmware (written in Arduino).
    • In addition to the firmware, you'll also need to add the SevSeg library to your Arduino install.
  • Hardware - The Eagle files are hosted here. Do you want to make your own version of the display? Go for it! This is an open-source project.
