Nextion touch screen projects
Nextion is a Seamless Human Machine Interface (HMI) solution that provides a control and visualisation interface between a human and a process, machine, application or appliance. Nextion is mainly applied to IoT or consumer electronics field. It is the best solution to replace the traditional LCD and LED Nixie tube.
Nextion includes hardware part (a series of TFT boards) and software part (the Nextion editor). The Nextion TFT board uses only one serial port to communicate. It lets you avoid the hassle of wiring. We notice that most engineers spend much time in application development but get unsatisfactory results. In this situation, Nextion editor has mass components such as button, text, progress bar, slider, instrument panel etc. to enrich your interface design. And the drag-and-drop function ensures that you spend less time in programming, which will reduce 99% of your development workloads. With the help of this WYSIWYG editor, designing a GUI is a piece of cake.
Nextion touch screen projects
Smart airhosts is concept to realize the automation in airhosts services. In this restaurant the kitchen people can get orders from each passenger through voice alert. This project consists of two sections one is transmitter section and other is receiver section. In our project we have designed an electronic system to order through RF based wireless communication using a menu card provided on each table. Touch panel is used here, which offers simple and multiple menus driven control panel. Mainly touch screen technology is used where control or settings of different parameters in wide manner. We can select the items shown in its display and can order the selected items through touch panel. The total cost of the items is also displayed. This order details are collected by wireless receiver placed in the airhosts compartment or kitchen and will announce the items in its display along with the voice announcement through speaker.
Touch screen based Appliances Control System is used to control various electrical appliances in our home using a touch screen panel. This project can also be used in industries and colleges. We have provided 5 relays and a buzzer. This project can control AC devices as well DC devices. We have provided 2 DC devices and a buzzer with this project for demo purpose. User has to use a touch screen which acts as control panel for sending commands. These control commands are sent through a wireless RF communication module.
In today’s world we have automation in all areas; there is one field where technology not entered yet. It is the menu display & ordering system & so far there is no initiative to taken to introduce
technology in this area.Touch-screen based advanced menu ordering is the method by which anyone will select any items by their choice which are in menu display & that order will be transferred to the cook or manager's personal computer using RF wireless transmission module & that ordered item will be given to that customer.
Touch screens as a popular user interface are more and more common. Applications span from public information systems to Customer self-service terminals. Thus, as a Logical step, more and more devices today Feature this kind of user interface, e.g. Bank Automatic teller machines (ATMs), personal Digital assistants (PADs), mobile phones and displays.A touch screen is a display that can detect the presence and location of a touch within the display area. Lets one do so without requiring any intermediate device, again, such as a stylus that needs to be held in the hand. Such displays can be attached to computers or, as terminals, to it networks. Therefore it is very suitable for restaurant & time saving. It enables one to interact with what is displayed directly on the screen, where it is displayed, rather than indirectly call the waiter & ordered the menu. These devices also allow multiple users to interact with the touch screen simultaneously. Touch based interfaces have been around for a long time in consumer electronic devices, and even longer in research labs, but it has only been recently that the wider public has taken a keen interest in this mode of human?computer interaction.
A touchscreen is an electronic visual display that the user can control through simple or multi-touch gestures by touching the screen with one or more fingers. Some touch screens can also detect objects such as a stylus or ordinary or specially coated gloves.
In this project a touchscreen is used as an input system to control the vehicle. The touch screen cannot be directly connected to the controller so a ADC is used in between. The controller after getting the signals from the touch screen will control the DC geared motor. We will be using 60 RPM DC geared motor. Since the controller cannot directly control the motor a Motor driver IC will be used to provide the necessary current and voltage to the motors.
An IR based obstacle sensor will be used to check for obstacles. IF any obstacle is detected the robot will stop automatically and a warning buzzer will be sounded.
