Google Assistant Controlled Scrolling Display

In this rapidly growing and developing world, the foremost aim of technology is to increase the efficiency and to decrease the effort. In this trending world, Internet of Things is given so much of importance. Hence by using IoT, we are successful in controlling various devices or appliances in this present world. And one such device is a matrix display, which is controlled using a NodeMCU. Various other modes such as raspberry pi or beagle board can used to do the same. The idea behind Google assistant-controlled scrolling display is to a matrix display with voice. In this project, the Google assistant requires voice commands. Adafruit account which is a cloud based free IoT web server is used to create virtual switches, that links to IFTTT website abbreviated as "If This Than That" which is used to create if else conditional statements. The voice commands for Google assistant have been added through IFTTT website. In this project, as the user gives commands to the Google assistant, the display, can be controlled or updated accordingly. The commands given through the Google assistant are decoded and then sent to the NodeMCU, the microcontroller in turn control the display unit connected to it. The disply unit updates as per the users request to the Google Assistant. The microcontroller used is NodeMCU (ESP8266) and the communication between the microcontroller and the application is established via Wi-Fi (Internet).
