In the era of digital transformation, Internet of Things (IoT)
and Internet of Services (IoS) have emerged as the major
components in Industry 4.0. In the IoT and IoS context, Web
Application (WebApp) raises as the world's most popular software
application that utilizes web technology and web browsers to
perform specific functions or tasks over the internet. In a lot
of IoT projects, web application is mostly used application for
the users to monitor or control their systems.
In this 8x8 RGB LED project, a rather unique web application
needs to be developed in order to fulfil the project requirements.
One of the requirements is the user able to control and play up
to 16 devices (16 8x8 RGB LED which are integrated to 16 ESP32
respectively). Therefore, a few features have been
developed so that the user can choose, control and play the 8x8
RGB LED. The features are such as Text Generator, Tap-to-Light
In addition to this project, the web
application should be able to communicate with ESP32 through an
IoT protocol and energy efficiency factor must also be
considered. Hence, a light and fast MQTT protocol is used and
the function to regulate the brightness of the 8x8 LED with the
help of LDR sensor is programmed. Finally, the web
application is fully developed and named 8x8-WebApp.
