How To Check Tuya Library in Arduino IDE

Hello there! I'm a newbie here, but I have a great love for Arduino and smart devices. I have tried a lot of types of devices using the same app (smart life) and tuya cloud. Officials say there are more than 200,000 SKUs; well I think they are quite cheap and widely distributed. However, it is hard to connect Arduino with Tuya cloud.

The Arduino support team answered my question and provided the support and demos. To make a long story short, the steps they gave me might be helpful for you:

You can use any Arduino development board and Tuya general Wi-Fi module to quickly implement network connections and develop your own IoT projects. You do not need to port the SDK.

This article describes how to use Tuya’s Arduino library.

Hardware Preparation

• Arduino development board.
• Tuya general Wi-Fi module or Sandwich development board (Wi-Fi communication board).
• Other peripheral devices depending on your requirements.

Sample code

Before using the Tuya library, you can run the sample code to better understand the application logic, facilitating further development.

• Extract the Tuya_WiFi_MCU_SDK software package and place it as a third-party library in the libraries folder under the Arduino IDE installation directory.
• Restart the Arduino IDE, and you can see Tuya_WiFi_MCU_SDK library in the third-party library.

Below, you can see that there are two basic examples in the Tuya library, helping you get to know how to use the Tuya library.

• Start: a basic example that contains a switch data point (DP). You can turn on or off the light through the mobile app.
• DataPointType: an example to report DP data to the cloud and send DP data from the cloud to the product, with six data types in total.

• Select a sample project and compile it correctly. Set the parameters and download port in the IDE as per your board, and download the routine to the board.
• According to the sample code, pull down pin 7 (key pin) on the Arduino board, and the board will send a repairing command to the module. When the command is sent successfully, the onboard LED_BUILTIN will flicker, indicating that the module enters the pairing mode. In this mode, you can use the Tuya Smart app to pair the module and check data communication after pairing.
  Well done! The sample code test is completed.

The above image shows the device control panel (debug mode) after the app has successfully paired with the module in the DataPointTypeexample.

And finally, if you tried the development on the Tuya IoT developer platform, you will find interesting functions on using and designing the APP to control your devices with zero-coding and a beautiful panel as well.
