# Grove - Four Digital Tubes Display
# Grove - alphanumeric Digital Tubes Display
***
## Introduction of sensor
Grove - Four Digital Tubes Display,it can display number,and scrolling displaying.
Grove - alphanumeric Digital Tubes Display,Based on HT16K33,it can display number,and scrolling displaying.
**Support dual(two tubes)&qual(four tubes) alphanumeric Digital Tubes simultaneously.**
***
## Usage:
Download all the source files.
There are four examples for user to use.
>* **example/display_custom/display_custom.ino**.
>* **example/display_scroll_string/display_scroll_string.ino**:Display scrolling string which longer than 4.
>* **example/display_scroll_number/display_scroll_number.ino**:Display scrolling number which bigger than 9999.
>* **example/display_basic/display_basic.ino**:Basic static display demo.
>* **example/display_custom_4/display_custom_4.ino**.Only support for qual(four tubes) alphanumeric Digital Tubes.
>* **example/display_scroll_string/display_scroll_string.ino**:Display scrolling string which longer than 2(4).Support dual(two tubes)&qual(four tubes) alphanumeric Digital Tubes simultaneously
>* **example/display_scroll_number/display_scroll_number.ino**:Display scrolling number which bigger than 99(9999).Support dual(two tubes)&qual(four tubes) alphanumeric Digital Tubes simultaneously.
>* **example/display_basic/display_basic.ino**:Basic static display demo.Support dual(two tubes)&qual(four tubes) alphanumeric Digital Tubes simultaneously
>* **example/number_increment_2/number_increment_2.ino**,Only support for dual(two tubes) alphanumeric Digital Tubes.
----
## select type of alphanumeric Digital Tubes Display
**You can switch dual/qual alphanumeric Digital Tubes Display by change the micro <DUAL_NUMERIC> in every example.**
```
//#define DUAL_NUMERIC
```
comment it ,using qual alphanumeric Digital Tubes Display,otherwise ,using dual alphanumeric Digital Tubes Display.
**defaule using qual alphanumeric Digital Tubes Display**
