==Connect to Arduino ==
==How to use on Arduino ==
*Step 1: Download the test program
# Download the Arduino test program from the Program Download column
# For a description of the relevant test procedures, please refer to the test program documentation in the package
*Step 2: Connect the Arduino development board
# Plug the module directly into the Arduino development board ( Do not plug in?)
# After the module is plugged in, power on the Arduino board
*Step 3: Copy the dependent library
# Make sure the Arduino IDE is installed on your computer (if it is not installed: Arduino IDE download URL)
# After installing the Arduino IDE, you need to copy the dependent library to the Arduino project directory as follows:
::(1) Decompress the downloaded test package
::(2) Copy the dependent libraries in the Install libraries directory in the package (shown below) to the libraries folder 
:::of the Arduino project directory （ Don't know the Arduino project directory?）
::
*Step 4: Compile and download the program to the development board
# Open the sample in the Example directory of the package to test, compile and download（ Don't know how to compile and download?）
*Step 5: Observe the running of the program
# After the program is downloaded, run it directly and observe the running status. If it can be displayed normally, the program runs 
::successfully, as shown in the following figure (take the colligate_test test program as an example):
