In every field of human life, automation has become more important. But there are also many areas where more common methods are being used. The restaurant ordering system is one such area.The goal of this project is to create a touch-based food ordering methd as well as a secure payment process which can be used to change the conventional ordering process. For general, the food ordering procedure as actually given in the menu card format in restaurant, then the customer will have to choose the food item, so the server would have to come back and take their orders, which is really a long method of processing. The paper recommended a completely integrated ordering system, in which a more user-friendly and touch - screen menu card replaces the conventional paper-based menu ordering process. A computer consists of a microcontroller which is connected to the input and output devices. The input device has become a touch - screen module placed on the monitor of the HMI (Human-Machine Interface) that takes feedback from the consumer and input from the microcontroller. The LCD output module in a kitchen and cashier or the manager system that displays the customer order. The RF transceiver module, as well as the cashier/manager system, connects to the table and kitchen system.On the HMI display, the microcontroller displays menu entries as well. At the receiving end, the chosen objects are shown on the LCD, and at the buzzer the latest order will be shown. . Payment can be made with the QR code after completion of your meals from your reserved seat. This technology requires no power from humans and saves time.

Managing water consumption is vital for life preservation. Knowing water and power consumption at homes can have a great impact water saving. This project presents an innovative home security control system, based on controlling door with power and water resource while increasing the added values for security applications. When we in front of the door the IR sensor sense the position and lock the door using key, automatically signal send to the microcontroller. It acts as a brain of the system. After receiving signal switch ON the relay circuit, OFF the power supply, shut off water line using solenoid valve. This would make the security process more efficient and convenient for house owners.

Fuel is one of the most important and recent crises in present situation. Though the people are working on to find out the alternative way to provide a better renewable energy source, the hike and need for coal and petroleum never stops. The transmission of petroleum and its products takes place only through the highways by means of tanker Lorries. Since the total quantity of the petroleum reduces as a result of carelessness and selling it to get more money, there exist a gap between the sender and the receiver. To avoid all those mischievous, our system provides a secured and compact device that can measure the amount of liquid in the container and transmits to sender as well as the receiver to avoid further chaos.

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.
