The Voice Controlled Notice Board is a computer controlled machine. This automated system can reduce the manual work. The construction of a simple and low-cost Voice Controlled Notice Board is addressed in this framework. The aim of this device is to create an automatic display board that is controlled by the Internet. This electronic machine is made up of both software and hardware components. The key goal of this device is to provide a remote notice board that faculty can use to post the most recent notices and announcements. The other goal is to improve contact speed while still saving time and money. It may also be used to increase the re - usability of existing designs and reduce the amount of space available, lowering costs.Wi-Fi-based cellular serial data networking is used in the proposed system. For Wi-Fi connectivity between an Android-based personal digital assistant and a remote wireless display screen, Android-based device applications are used. In this design, messages are sent through an Internet from an authorized transmitter and then message is transmitted to the Node MCU and the message is read and sent to digital display board.

An IoT based smart programmed multi cropping water system control gadget has been intended to encourage the automatic water supply of adequate water from a sump or well to field or multi cropping crops in all agricultural season. One of the main objective of this project is to avoid manpower for every irrigation purposes with proper interval based on multi cropping system. The technique utilized is to consistently monitor the real time gap and crop duration, fertilizer duration for feed to cropping system. And also how much water is required for each different kind of crops in multi cropping system. The pump motor will operate based on the microcontroller system output. The different valve system will operate by proper relay driver system for dripping the individual cropping system. The exclusive android application will help and monitor the real scenario for dripping system. The application is running based on the customer input data, once owner feed the data will stored in cloud and the microcontroller will get the data from cloud and control the valve systems. The manual setting system also included in this gadget. The arduino board is specially designed circuit board for programming and prototyping with ATMEL microcontroller. The microcontroller used in this arduino is ATmega 328 which is in-built in arduino board and the coding are done in embedded C.
