IoT Based Real Time LED Display Board

The Evolution of Technology made Human life easier where we can compare the timeline of using landline and smart phone, right now every human being is surrounded by smart gadgets where human interference has reduced to perform mechanical works. The physical work effort is high for advertising or passing a notice throw a paper, this kind of problem is outplayed by using micro controller based digital LED boards, in this system the message is programmed into the microcontroller which is wired to LED board the microcontroller will pass the message to LED board where led board will display the message. This LED displays are becoming primary need in heavy crowded places such as malls, railway stations, educational institutions to display information regarding offers, platforms or important notices. To change the message in microcontroller we have to reprogram it every time we can outplay this scenario by integrating it by new wireless IoT technology. This paper will paper the development made in IoT based real time LED display board by using esp32 and Arduino.
