Social Stats Tracker for Twitter, Instagram, Instructables

Frame your followers! Here’s how to build a social media stats tracker display using the a wifi arduino-compatible ESP8266 microcontroller board and several seven-segment displays. This project is an extension of my YouTube Subscriber Counter project, but uses one “brain” to track and display multiple networks. Easily omit the left (large digits) displays for any stat under 10k to bring the cost of components down.

Before attempting this project, you should be generally familiar with uploading new programs to your Arduino board and installing code libraries, both of which you can learn for free in my Arduino Class, though you really don’t have to understand much of the actual Arduino code to get this project running.

For a more in-depth introduction to the ESP8266 board (and its installation and setup), check out my free Internet of Things Class.


For this project, you will need the following materials:

and the following tools:

Required software libraries (all searchable through the Library Manager):

Unique data required:

  • Twitter API bearer token (read Brian’s instructions for getting this)
  • usernames for Twitter, Instagram, and Instructables
  • Wifi network name/password

As an alternative to the NodeMCU board, you can also use your favorite ESP8266 microcontroller board, some of which require a 3v FTDI programmer to upload new programs.

Before you dive into this project, you should first make sure you’ve got your Arduino software set up properly to program the board you are using, which in my case involves installing the SiLabs USB driver and installing ESP8266 board support (explained in more detail in my Internet of Things Class):

  • Go to Arduino-> Preferences…
  • Look for a text field labeled “Additional Boards Manager URLs:” and paste the following URL into the field (separate multiple URLs with commas if applicable):
  • Click OK
  • Go to Tools->Board-> Boards Manager…
  • Search for ESP8266 and click the Install button in the box “esp8266 by ESP8266 Community” when it shows up

To ensure you have a proper programming connection with your board, first load up the blink sketch. You can find a sample blink sketch by navigating to File->Examples->ESP8266->Blink, or copy it from here:

void setup() {
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);
  digitalWrite(LED_BUILTIN, LOW);

Plug in your USB cable to the board and configure your settings under the Tools menu as follows:

  • Board: NodeMCU 1.0
  • CPU Frequency: 80MHz
  • Flash Size: 4M (3M SPIFFS)
  • Upload Speed: 115200
  • Port: whichever one ends in SLAB_USBtoUART (Mac) or COMx (Windows)

Click the Upload button to send the program to your board. This will take several seconds (longer than you are used to with Arduino Uno). After complete, the onboard LED should start blinking.

While many boards auto-detect when they’re being sent a new program, some other ESP8266 boards may require a sequence of button presses to get into bootloader mode.

Do not proceed until you’ve successfully uploaded a blink test program to your board. Seriously, because how can you expect the project code to upload if the test didn’t? =D

Prepare Displays & Prototype

Follow the assembly instructions for your seven-segment displays, and also solder headers onto your ESP8266 board if it didn’t come with headers pre-soldered.

For your microcontroller to tell the different displays apart, you’ll need to change their addresses. Do this by applying a blob of solder to bridge the labeled pads on the back of the board. The board as-is has an address of 0x70, and if you bridge A0, it has an address of 0x71. More info on i2c addresses in the official product guide. Here’s how the displays in my circuit/code are configured:

  • 0x71 high digits Twitter, A0 shorted
  • 0x70 low digits Twitter, no alteration
  • 0x74 high digits Instagram, A2 shorted (not installed)
  • 0x73 low digits Instagram, A0 and A1 shorted
  • 0x75 high digits Instructables, A0 and A2 shorted (not installed)
  • 0x72 low digits Instructables, A1 shorted

When working with electronics, I always like to create a solderless prototype first. Download the code attached to this step (big thanks to Brian Lough for writing all those awesome Arduino libraries).

I’m using a NodeMCU board this time, but any ESP8266 board with the I2C pins exposed will work fine. In my case that’s D1 and D2.


  • NodeMCU D1 to displays C (clock)
  • NodeMCU D2 to displays D (data)
  • NodeMCU Vin to displays + (power)
  • NodeMCU GND to displays – (ground)

Assemble With Paper Template & Shadowbox

Download the paper template attached to this step or create your own 5×7 artwork to fit in the front of the shadowbox frame. This template also contains an alignment helper, which you can tape directly to or use as a reference for taping the displays directly to the back of the front-facing printout. The thickness of your paper will determine your light throughput and circuit sturdiness, so feel free to play around with the combo of layers and thicknesses of paper that work best for you.

I soldered my multi-display counter (Twitter only) to a perma-proto board to keep them aligned, and plugged female header wires into the single display headers. The NodeMCU board gets its own small perma-proto, where I soldered more wires to plug into all the various displays. This keeps the project modular in case I want to take it apart or add more displays later.

Close Up the Circuit

Use some cardboard or other stiff material to brace against the back of each display before installing the back cover (use scissors to cut a notch for the USB cable). It took me a few tries to get the displays pressed evenly against the artwork/glass to create crisp digits. If they’re not pressed tightly or evenly enough, the numbers will appear blurry.


Display your project and track your growth! I love having these displays hanging above my workbench to inspire me to keep making and sharing fun projects with all of you. Thanks for reading!

I’d be delighted to see your tracker displays in the comments below, as well as to hear your thoughts, questions, and feedback.
