Scrolling Text Display on 8x8 LED Dot Matrix using NodeMCU

Abstract

Generally we use simple led regular static type display screen to deliver the message. Previously, to update the data either it may be large one it takes a long process to update data. Now a days scrolling type displays are more preferred over the static type displays. By adopting a programming device called NODEMCU, data can be displayed on dot matrix in scrolling manner. By adopting led 8x8 dot matrix using can controlled via IoT based system which controlled by mobile or laptop. Scrolling type text display boards, projects uses led dot matrix displays or regular outside purpose digital sign boards. The message scrolling displays are also type of scrolling LED display examples, presented here are nodemcu based led matrix display project. The led matrix is controlled using nodemcu by serial communication protocols. In this pair of 8*8 led Matrix display modules have used to display the transmitted message on Matrix display. nodemcu is heart of this project. The nodemcu is the transmitter to send data, and the receiver is led matrix display to display message on it.
