This is Lite version of Neoconverter Pro (https://play.google.com/store/apps/details?id=com.VitoGusmano.NeoConverterPro).Neoconverter is the definitive guide on the creation of LED matrices with Neopixel WS2812B controlled by Arduino (Nano) and ESP8266-01 so that you can manage everything on the net with WiFi.In this guide you will find all the instructions to create a WS2812B LED matrix, so you will have the list of components to use, schemes to create your circuit and finally the possibilities offered by Neoconverter, which, create sliding text lists, images and effects, including visualization of hour and date.Neoconverter creates a database in your mobile phone where you can store your controls in different lists. The possible types of commands are sliding text, image and effects. The play and stop buttons are used to start playing the control list on led matrix or stop it in real time. All without ever programming Arduino or other hardware, once downloaded to Arduino and Esp8266 the software that you can download through the application, the game is done.Why use neoconverter?On the net there are hundreds of tutorials to create an LED matrix with the Ws2812b and Arduino.Once you go into these tutorials, different problems come out, like, Arduino has too limited a memory, requires medium-advanced computer skills to be managed and is clear from the first examples that are on the Internet, which you cannot have infinite Images on your LED matrix, or memorize infinite sliding writings. Furthermore, whatever programs on your Arduino cannot be changed in real time unless you use very few data to store it. It is clear that by "infinite" we mean a considerable quantity of sliding text, images and effects that normally cannot be programmed due to the low amount of memory available with Arduino. The gap is overcome using an Android device (today equipped with a considerable memory ..) which will allow you to store your data on database in an organized, modifiable and displayable way in real time.
