IoT of Nextion X TFT ILI9341: Experimental Results and Comparative Survey

Abstract

This study presents the results obtained in experimental and comparative research, between the Nextion and TFT devices ILI9341, carried out in 2017, focusing mainly on the positive and negative points presented by the different devices when using a touch screen display for Arduino. The methodology used to obtain the data was experimental research with the devices, applying for the systematic review, considering personal experience when using these types of equipment. After obtaining the data was proceeded to consolidate, categorize and analyze the quantitative and qualitative results. There was a perception about the results that point out the pros and cons on the different technologies, among these areas: the ease of creating interfaces to the screen; the ease of configuration and installation, as well as the quality of the products and their prices. In counterpoint, the Nextion device presented a higher cost compared to the TFT devices ILI9341, the main difference between the two devices is in: their prices; ease of solutions creation. In addition to the use of Arduino board resources, in these requirements, the devices Nextion presented better results, as presented in this study.

Comparative research in the field of professional education of preschool teachers: comparative content analysis as a method of authentic interpretation of concepts

“…The Ukrainian term "pedagogychna pidgotovka" is correlated with the English version of "teacher education", which is more typical of the European scientific tradition than "pedagogical education", as the latter phrase is a tracing paper from Ukrainian into English. In the UNESCO glossary, the category "teacher education" is understood as the formal training of teachers (before professional activity), which is designed to provide teachers with the amount of knowledge necessary for professional activities, values, and involves the formation of professional behaviour and skills needed to organise the educational process according to levels of education (Surahman, 2020;Bento, 2018).…”

Utilization of atmega328 PIR and microcontroller sensors to improve CCTV online performance

“…The schematic circuit design tool consists of a minimum ATmega328 microcontroller system, a PIR sensor as an input device, buzzer, and speaker as an output device controlled by ISD1820. Input devices are sensors which are the source of commands for the microcontroller (Bento: 2018). Normal conditions PIR sensor logic 0, if the sensor detects the movement of the object then the PIR sensor is logic 1.…”

Comparison of Air Pressure Control Between Discrete and PID Control Applied in the Calibration Process in Blood Pressure Meter

“…Arduino Uno microcontroller is used to process analog data into digital data that is displayed on the TFT LCD [23]. The TFT device presented by Adafruit is one of the most inexpensive and easy to find devices for purchase, both national and international, easily accessible nationally and at a very affordable price, this device is the most common for use with projects for Arduino, or for the internet of things [24]. TFT Nextion LCD serves as a display to display the measurement, calibration process [25].…”
