IoT Scoreboard Using Teensy and ESP8266 with Blynk App

Introduction

Did you have experience handling scoreboard in any tournament? Now you can make it more interesting by control it through internet. This tutorial using Teensy as a main microcontroller and ESP8266 as a WiFi module. I’m using NeoPixel LED panel 8×32 as a display that require only 1 GPIO! To control it, you need an Android or iOS smartphone with Blynk app installed. Let’s try!

Video

This video shows how to create an IoT scoreboard using Teensy (Arduino) and ESP8266 with Blynk app.

Hardware Preparation

This is the list of items used in the video.

The custom PCB is created using CNC on Snapmaker. Below is the list of components used in the PCB.

Schematic and PCB files

If you have Snapmaker, you can download 👉 THIS FILES, and use it for CNC your PCB.

Sample Program

This is Arduino sample program for Teensy board. Before compile, please install following libraries through Library Manager:

  • Blynk by Volodymyr Shymanskyy Version 0.6.1
  • Adafruit GFX Library by Adafruit Version 1.7.5
  • Adafruit NeoPixel by Adafruit Version 1.3.4
  • Adafruit NeoMatrix by Adafruit Version 1.1.4
