Designing lighting product prototype (PWM, development free)

Last Updated on2020-08-06 03:07:05

Overview

Technology is constantly progressing, and more and more smart homes are entering our daily life. Smart lights are commonly used at home and the workplace.

After the smart lights are installed, you can easily adjust the indoor color and brightness by using App, and can set different lighting scene for different occasions, creating a warm, relaxing, interesting and inspiring living space, which greatly enriches our lives.

Based on the Tuya Smart platform, a smart light can be developed simply and quickly. This tutorial introduces how to use the Tuya sandwich development board to quickly complete a smart light product prototype.

  • Step 2: Downloading firmware

    To make the device have the configuration function of the first step, you must download the relevant configuration information into the module, and attach it to Tuya Sandwich Evaluation Kits,

    1. Visit the Tuya sandwich development board management platform, and register the development board, apply for an authorization code and an account.

    2. Choose the authorization code, log on the software, and enter the authorization code to download. For more information, see Download firmware and authorization code process.

  • Step 3: Network configuration test of App

    In this demo, the control light is powered on and off for three times.

    If the light flickers rapidly, it enters the network configuration state. You can connect and use it via Tuya Smart app, choose lighting (Wi-Fi) category, for the next operation under the orders of the APP, connect the device to the cloud, you can use the App to control the device now.

    You can view the brand of the speaker at the product details page. Subsequently, you can refer to the Quick Guide of Using Amazon Echo to Control Smart Devices to grant the device to the smart speaker platform. Also, you can use the smart speaker to control the device, for more information, see Third-party Access.

  • Step 5: Production test for extended function

    During mass production, you must test the communication and control capabilities of the products to spot the defective products, and guarantee the quality of the products. Tuya integrates the test process at the time of production into the module, for more information, see Production test of Wi-Fi lighting products.

Summary

Based on the Tuya platform and the Tuya sandwich development board, the prototype construction of a smart lighting product can be completed quickly and conveniently, which greatly accelerated the development of the product.
