Abstract - With the increasing in technology everything around us becoming smart. This leading to the development of new electronic devices for ease use. Keeping a view on this we are designing and developing an notice board which is handled digitally by using IoT technology with android mobile application. The primary objective of this project is to develop automatic, highly reliable and self enable led notice board. The DMD connected with the cloud will continuously waiting for the message from the user, if the user uploads the information in the MQTT mobile Application, it will automatically uploaded to the DMD. By using Node MCU ESP8266, the information can be upload to the DMD. The user can write the information from anywhere in the world to the DMD. Along with displaying important information on LED screen it can also provide voice assistance feature which makes it more attractive to use. This voice assistance is enabled by using Raspberry Pi. This will reduces the time to update the information and efficiently transfers the information to the end user.  This is best suitable wireless notice board works with internet connection as the wireless world moving towards the fifth generation (5G) era.
