In this project I will show you how I combined 4 inch 7-segment displays and an ESP8266 Wifi module to create an 8 digit display that can present your most important data from the internet. Let's get started!

Step 1: Watch the Videos!

The two videos give you a detailed overview on what you need to do to build your own "Internet Display". But I will present you some additional helpful advice in the next steps.

Step 2: Order Your Parts!

Step 3: Build the Circuit!

Here you can find the circuit as a picture and/or the Eagle .sch and .brd files to make your own professional PCB.

Step 4: Upload the Code!

Here you can find the code that I created for this project. Make sure you include the tlc5940 library and update the number of used TLCs: https://code.google.com/p/tlc5940arduino/
