Design of Wi-Fi Based Scrolling Digital Display with Voice Command Support by Google Assistant

Abstract

Abstract: The purpose of create this paperwork is that it represents the overall design of “Scrolling Digial Display” which has a capability to control the display over mobile phone using voice command. It also included various software like Adafruit MQTT and IFTTT and a platform for voice command we have to use Google assistant. If someone want to display message using Arduino, they can easily send by using this project. This paper deals with wireless board or a LED dot matrix display using any android phone using Wi-Fi module (Wireless fidelity basically it transfers message without using wire network or bulk machines. Schools, colleges, hospitals, traffic signal, Hotels, Railway station, Airport and various other places there is use of scrolling display to display the message at the receiver end and this tool kit can be programmed according to our need. Keywords: Adafruit, MQTT, IFTTT, LED dot matrix, Scrolling display, Wi-Fi module, VPA (Voice personal assistant).
