Have you ever wanted a marquee display to output your latest message to people walking past your business or office? Or perhaps a display to show you the temperature or time at a moment’s notice would be useful to you.
This can and has certainly be done with the right combination of dev board, display, communications hardware, and programming. For an all-in-one solution, however, Armtronix is offering a WiFi sensor board along with a 32×16 display and power supply in a convenient kit. The sensor board includes the same ATmega328P microcontroller used in the Arduino Uno (and many other applications), along with the an ESP8266 module for communications.
As seen in the video below, the setup is ideal for receiving text from a smartphone and displaying it, and includes a RTC and headers for a variety of sensors. This means you’re not restricted just to static text, or even info pulled from external sources for your array of 512 LEDs.
