Executive Summary

In this project, I took my BeagleBone Black and a LED matrix from Adafruit and created a clock that shows the current temperature outside.


If you have hardware, consider Small Build, Big Execuition for ideas on the final packaging.

Installation Instructions

GitHub: The repository for this project can be found here. BBB_Led_Matrix_Info_Board

Hardware: Below are the following products used to complete this project.

Installation Start off by going to the link here Falcon Christmas Player and download the BeagleBone Black image. Next follow the instructions on on the following page to get the Beagle set up and connected to the internet. Out of the Box, Bone Note: When following Mark A. Yoder's instructions the Falcon Christmas Image doesn't have the same username and password as the one in Out of the Box, Bone. The username and password are as follows:

  • username: fpp
  • password: falcon

Note: Every time you type debian in the setup, it needs to be replaced with fpp.

With that done and out of the way, if you wish to run the program completely on the bone, you can ssh into it and clone the repo at this time. You can also run the program on a host computer as well without being connected by ssh, so if you wish to run it this way go ahead and clone the repo to your host computer now Next we need to work on the hardware part of this project before we continue with the software.

Cape Construction

It is possible to connect the LED matrix to the beagle with breadboard wires, but if you don't want to worry about wiring it wrong, or will want to unplug it often it is nice to have a cape for this. If you wish to not continue with cape construction, continue to the wiring diagram below. To start off constructing the cape, take one of the 8cm proto boards from the link above and cut off one end of the board that has the surface mount pads; cut all the way to the to the exposed copper of the first row of holes.(See photo of completed cape for a better idea of where to cut) Next, take four rows of 26 header pins and solder them in place so that they will go into the P8 and P9 headers of the beagle. Once completed take two rows of 8 header pins, stick them into the top of the cape and solder them from the underneath side, we will solder wires to these next.

Wiring diagram for the cape.

User Instructions

Once everything is installed, how do you use the program? Give details here, so if you have a long user manual, link to it here.

Consider making it autostart for full credit.


Here is where you brag about what your project can do.

Include a YouTube demo the audio description.

Theory of Operation

Give a high level overview of the structure of your software. Are you using GStreamer? Show a diagram of the pipeline. Are you running multiple tasks? Show what they do and how they interact.

Work Breakdown

List the major tasks in your project and who did what.

Also list here what doesn't work yet and when you think it will be finished and who is finishing it.

Future Work

Suggest addition things that could be done with this project.


Give some concluding thoughts about the project. Suggest some future additions that could make it even more interesting.
