Technical requirements
The following hardware components are required to complete this chapter’s exercise:
- Seeed Studio XIAO ESP32C3
- USB type-C cable for XIAO ESP32C3
- WS2812 RGB LED ring
- Male headers, female headers, and a veroboard
- Jumper cables
- Soldering iron
- Amazon Echo Dot and the Amazon Alexa mobile app
For coding, we will use the Arduino Web Editor, which includes a large collection of development boards and sensor libraries, and the Arduino IoT Cloud for the Thing and dashboard setup. To develop hardware and sensor designs, we need the Fritzing desktop software and the Arduino IDE for testing the WS2812 ring.
Here, we will use the Amazon Echo Dot as a voice assistant for voice commands to control the smart bulb. If you don’t have an Echo Dot, then you can use the Amazon Alexa app for Android/iOS. The chapter’s code is available in the official GitHub repository for the book by following this link: https://github...
