Install Arduino IDE and Driver
（1）Installing Arduino IDE
When we get control board, we need to download Arduino IDE and driver firstly.
You could download Arduino IDE from the official website
https//www.arduino.cc/, click the SOFTWARE on the browse bar, click “DOWNLOADS” to enter download page, as shown below
There are various versions Of IDE for Arduino, just download a version that compatible with your system, here we will show you how to download and install the windows version Arduino IDE.
There are two versions of IDE for WINDOWS system, you can choose between the Installer (.exe) and the Zip packages. We suggest you use the first one that installs directly everything you need to use the Arduino Software (IDE), including the drivers. With the Zip package you need to install the drivers manually. The Zip file is also useful if you want to create a portable installation.
You just need to click JUST DOWNLOAD.
（2） V4.0 Development Board
We need to know V4.0 development board, as a core of this kit.
V4.0 development board is an Arduino board, which is based on ATmega328P MCU, and with a cp2102 Chip as a UART-to-USB converter.
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz quartz crystal, a USB connection, a power jack, 2 ICSP headers and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it via an external DC power jack (DC 7-12V) or via female headers Vin/ GND(DC 7-12V) to get started.
（4）Installing V4.0 board Driver
Let’s install the driver of V4.0 board. The USB-TTL chip on V4.0 board adopts CP2102 serial chip. The driver program of this chip is included in Arduino 1.8 version and above, which is convenient. Plug on USB port of board, the computer can recognize the hardware and automatically install the driver of CP2102.
If install unsuccessfully, or you intend to install manually, open the device manager of computer. Right click Computer----- Properties----- Device Manager
There is a yellow exclamation mark on the page, which implies installing unsuccessfully. Then we double click the hardware and update the driver.
Click “OK” to enter the following page, click“browse my computer for updated driver software”, find out the installed or downloaded ARDUINO software. As shown below
There is a DRIVERS folder in Arduino software installed package, open driver folder and you can see the driver of CP210X series chips.
We click “Browse”, then find out the driver folder, or you could enter “driver” to search in rectangular box, then click “next”, the driver will be installed successfully. (I place Arduino software folder on the desktop, you could follow my way)
Open device manager, we will find the yellow exclamation mark disappear. The driver of CP2102 is installed successfully.
（5）Arduino IDE Setting
Click the Arduino icon to open Arduino IDE.
To avoid the errors when uploading the program to the board, you need to select the correct V4.0 Board or MEGA 2650 Board that matches the board connected to your computer.
Then come back to the Arduino software, you should click Tools→Board, select the board. (as shown below)
Then select the correct COM port (you can see the corresponding COM port after the driver is successfully installed)
Before uploading the program to the board, let’s demonstrate the function of each symbol in the Arduino IDE toolbar.
A- Used to verify whether there is any compiling mistakes or not.
B- Used to upload the sketch to yourV4.0 Board or MEGA 2650 Board*1 .
C- Used to create shortcut window of a new sketch.
D- Used to directly open an example sketch.
E- Used to save the sketch.
F- Used to send the serial data received from board to the serial monitor.
（6）Start First Program
Open the file to select Example, choose BLINK from BASIC, as shown below
Set board and COM port, the corresponding board and COM port are shown on the lower right of IDE.
Click the Check Button to start compiling the program, check errors.
Click the arrow button to upload the program, upload successfully.
Upload the program successfully, the onboard LED lights on for 1s, lights off for 1s. Congratulation, you finish the first program.
How to Add a Library?
What are Libraries ?
Libraries are a collection of code that makes it easy for you to connect to a sensor,display, module, etc.
For example, the built-in LiquidCrystal library helps talk to LCD displays. There are hundreds of additional libraries available on the Internet for download.
The built-in libraries and some of these additional libraries are listed in the reference.
How to Install a Library ?
Here we will introduce the most simple way for you to add libraries .
Step 1 -After downloading well the Arduino IDE, you can right-click the icon of Arduino IDE.
Find the option "Open file location" shown as below
Step 2 - Enter it to find out libraries folder, this folder is the library file of Arduino.
Step 3 - Next to find out the “libraries” folder of this kit
You just need to replicate and paste above libraries into the libraries folder of Arduino IDE.
Then the libraries of this kit are installed successfully, as shown below
