ATTENTION:

- This app does NOT work with CH340 Chinese Arduinos (the very cheap ones).
- The connection between Arduino and cell phone is ONLY with an USB OTG cable or adapter. The cell phone used must be USB OTG compatible.
- Please read the "Important information ..." that comes in the app.
- For two of the three options available in this version, you must record the Arduino program (included in the app) and use a suggested circuit (schematic included in the app).

Today many people use wireless communications between Arduino and cell phone, however few options exist for USB OTG.
This application seeks to create an interface between the user and the Arduino platform through three options.

The first option is "LCD". Why spend on acquiring LCD screens, if you already have one always carrying in your pocket? Save money and replace them with your cell phone screen !! An example of how to use it is given in the Arduino program (included in the app). This option requires to record the program (included in the app) into Arduino board and follow the recommended circuit (also included).

The second option "Control of digital outputs in Arduino" independently controls 5 digital outputs of the board. What you control with these 5 outputs goes from to turn on/off simple LEDs, until motors !! The limit is your imagination. In a later version is intended to include all outputs. This option requires to record the program (included in the app) into Arduino board and follow the recommended circuit.

The third option "Serial Monitor" aims to recreate the function of the same name from the Arduino IDE. It can be used with any program recorded on the board that requires displaying information on the cell phone. The only speed it works with is 9600.
