Guide: The last section we learned how DIY smart switch, today we will learn how to control the infrared remote control appliances in the home, such as air conditioning, TV, set-top box, fan, etc.
This time we still use the Nano development board as a controller to build hardware with the fastest speed.
Here is our main accessories that we need to use:
Other accessories include: Micro USB line X1, 9V ~ 12V / 1A power adapter X1, 1P DuPont line 2
Insert the NRF24L01 module to the corresponding interface on the Nano Io Shield board, and then connect the NANO to the SHIELD slot, buttons the module to the electronic block interface of D2, the IR receiving module receives the electronic block interface of D5, and then The short pin of the IR transmitted diode is connected to the long pin to D3. The actual circuit diagram is shown below:
The button module is used to learn infrared coding.
The hardware is so fast, and next is to install the drive and burn the firmware.
NANO driver and library file Download address: http://pan.baidu.com/s/1nt5fy3j (copy to browser open) Download complete.
NANO Drive Installation Steps: Like the steps of temperature and humidity, students who have already installed NANO can skip this step.
a, plug in Nano with Micro USB cable connection computer
b, right-click "My Computer" or "Computer" to open "management"
c, enter "Device Manager", "USB Serial Port" appears under port COM
D, right-click "USB Serial Port", select "Update Install Driver Software"
e, click "Browse Computer Find Driver Software"
f, select the folder in the NANO driver file you just decompressed.
g, click OK or Next, complete the driver installation
Next, write the firmware for the NANO (you can modify the source code at will to achieve the function you want)
1. Put the downloaded library to the Libraries folder under your Arduino IDE directory, for example my path is: D: \ Arduino-1.0.4 \ Libraries
2, open Arduino software, choose Tools->Serial Port->comX
3, Comx is the COM number of the computer device manager CP2102
4, choose Tools->board->ardeno Duemilanove W / Atmega328
5. Copy the source code of Hongwai.PDE file (opened by Notepad) to the Arduino program interface
6, add new infrared equipment to "TV / air conditioner / home appliance" in http://m.znck007.com/ platform, remember its SID
7, modify the SID in the program to the new SID
8, finally click on the right arrow, start downloading the program.
9. When the green schedule is completed, there is a Done Uplineing instructions.
Next is to learn infrared remote control code. Current self-study coding includes NEC, Sony, RC5, RC6, and other no support.
Because our Oaks air conditioning coding does not support, we found an infrared remote switch to do experiments, of course, you can also try the air conditioners, infrared fans, and other models.
Learn Infrared Coding Method: After plugging in Nano Io Shield, restart the motherboard, then press the button module to make it enter the learning mode. Align the infrared remote control The IR receiving module, press, wait for 3 seconds, release the button module. After learning.
Finally, the networked test:
A, first, connect the gateway to the gateway, plug in the power adapter, the LED on the iBoard starts to flash, this shows that there is a network.
b, open the smart game controller m.znck007.com with your mobile phone or PC page, and log in to your account
c, put the IR transmit diode to the infrared remote control socket, use the mobile phone to click the infrared control icon of the Causa platform
