Application of DP 5125 IC and W00V7.0.2 Microcontroller on Android-Based Running Text

Abstract

Currently, lights with a series of running text based on Android applications are widely used in various places, especially vital public facilities such as educational facilities, hospitals, health centers, places of worship to government and private offices and shopping centers. Running Text is used as an information board, directional indicator or as a marker. In this study, the running text uses 24 main components of the DP 5125 IC and a W00V7.0.2 5V. microcontroller combined with  a power supply that produces  an output voltage  of 5 Volts and  1536 red Light Emiting Diode (LED) lights  . The series consisting of  a Printed Circuit Board (PCB) length of 1000 mm and a width of 200 mm can be operated through a mobile phone using an android-based application "Display LED or LED Scroller - LED Banner" which can be downloaded through Google Playstore. With this application we can operate or create a series of running text as we wish.
