KS0085 Keyestudio Smart Home Kit for Arduino

Instruction:

Smart home is the trend in the future. Imagine that you lie on the sofa and control everything with an ordinary cellphone. So incredible! The curtains can be switched automatically, the water temperature can turn into temperate mode when you’re ready for a cozy bath. Alternatively, you could obtain the distinct light scene in your home. I believe that you can’t wait to live life like this. In this lesson, we simulate the smart home to make a DIY smart home kit with Arduino software. Follow us to enjoy the joy of DIY!

Kit List

Download software and install driver

Download software

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 for Arduino, just download a suitable version for your system, we will take WINDOWS system as an example to show you how to download and install.

There are two versions for WINDOWS system, one is installed version, another one is download version, you just need to download file to computer directly and unzip it. These two versions can be used normally. Choose one and download on your computer.

You just need to click JUST DOWNLOAD, then click the downloaded file to install it. And when the ZIP file is downloaded, you can directly unzip and start it.

Keyestudio PLUS Control Board

Description

Keyestudio PLUS control board is fully compatible with Arduino IDE development environment. It contains all the functions of the Arduino UNO board. Moreover, some improvements we made highly strengthen its function. It is the best choice to learn how to build circuit and write code as well. Let’s get started!

Serial communication interface: D0 is RX, D1 is TX PWM interface (pulse width modulation): D3 D5 D6 D9 D10 D11 External interrupt interface: D2 (interrupt 0) and D3 (interrupt 1) SPI communication interface: D10 is SS, D11 is MOSI, D12 is MISO, D13 is SCK IIC communication port: A4 is SDA, A5 is SCL

Installing driver

Let’s install the driver of keyestudio PLUS control board. The USB-TTL chip on PLUS 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 the driver of CP2102 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.

Arduino IDE Setting

Click icon，open Arduino IDE.

To avoid the errors when uploading the program to the board, you need to select the correct Arduino 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)
