NodeMCU12e + Nextion Tft an Experimental Survey with Virtual Keyboard in IoT Projects

This manuscript presents the results of an experimental research on the construction of virtual keyboards for the Internet of Things (IoT), using the NodeMCU12e controller in conjunction with the Nextion touchscreen display. The creation of projects for the Internet of Things is in constant development, applying technical and scientific models that meet the different types of solutions, in this way, the results of this experience are presented during the construction of a solution that serves parts of academic projects, contributing in this way as a research base for more complex projects, which require a solution with virtual keyboard for data entry, or even for the configuration of different types of devices, such as Arduino or Raspberry Pi controller. With the results obtained with this study, it was possible to make feasible the construction of a proposal that meets the needs of a small project, allowing to expand its possibilities and resources according to the need of the project to be developed.
