This project was a collaboration with my roommate, friend, and fellow hacker rishi2. Living in New York, we both use public transportation daily, so we thought it would be cool to have a ticker to display bus and subway times from the internet. This is the result.

Step 1: Wiring It Up - Overview and Sources


1) Arduino Yun Microcontroller - http://www.arduino.cc/en/Main/ArduinoBoardYun?from=Main.ArduinoYUN

Our Yun is requesting messages from our web server over the internet and passing those message to the LED matrices. Both steps of the procedure are coded in a single loop that makes use of different libraries for sending/processing HTTP requests and controlling NeoMatrix matrices.

We started by reading the docs at the link above, then read through this getting started guide: https://www.twilio.com/blog/2015/02/arduino-wifi-getting-started-arduino-yun.html

2) Adafruit Neomatrix LED matrices (3) - https://www.adafruit.com/products/1487

The LED matrices display whatever we send to them from the Arduino. Each matrix has 64 individually addressable pixels that can be set to color on the RGB (255, 255, 255) scale. They are big time fun to play with.

If you want to use them in a project...

Very helpful tutorial we followed: https://learn.adafruit.com/led-art-with-fadecandy/wiring-your-leds

<p>Hey ... gud work !</p><p>How to get this working with Dot Matrix Displays that are available in market ?</p><p>They are equipped with 16-pin header for connection to controller board .</p>
Been looking for something like for awhile. Wanted to something bigger. 3x3 foot picture frame but this is a great start to get me going! Thanks will try
<p>Nice job! How did you put the youyube videos with autoplay and with no border and no controls?</p>
<p>Thanks! I followed this steps in this very helpful Instructable - https://www.instructables.com/id/Using-Youtube-psuedo-GIFs-to-an-Instructable/ :)</p>

<p>Woah! I want to make something similar in my high TV cabinet! I don't know if you read my mind or I read your instructable before! ;-)</p><p>Many thanks for the ideas and solutions!</p>
<p>Might be more tempted to hook it to a parallel port of a headless server.</p>
<p>not sure I follow? you mean connect the LED boards directly to the server?</p>
<p>yes.</p>
<p>I got a couple of graphical VFDs out of some old medical equipment (<strong>Noritake GU256x64-39)</strong> I've been meaning to do something like this. Also pretty simple with a USB cash register pole</p>
Want this!!!!!
<p>you should make one!</p>
If I could high five you I would.
<p>haha thanks!</p>
