Arduino Live Wifi Web Scoreboard

In this tutorial I am going to explain how I created a digital scoreboard with LEDs, a large dot-matrix display and numerical 8-digit totals. The device uses a WiFi chip to connect to the Internet to get status values such as totals and live counts, plus statuses such as on/off for the LEDs. The device is powered by a generic USB power adaptor. Under the hood it uses an Arduino Mega compatible board, which are readily available, economical, and communicate well with the ESP8266 chips.
The scoreboard is made from a wooden box, with hinges and a clip to allow for access to the internals when needed. Power usage is minimal, running the device 24/7 for a year with WiFi connections every minute will cost less than 1 euro.”
