Step by step
The workflow
Follow the sequence once, then adapt the prompts, checks, and handoffs to your own setup.
5 steps
Step02
Build a Control Application
Prompt the AI to build a web application that can connect to the device via Bluetooth and control its basic functions, such as drawing on its pixel display.
Step03
Create a Command-Line Interface (CLI)
Instruct the AI to then build a CLI to allow for programmatic control and sending commands to the speaker, abstracting away the low-level connection details.
Step04
Test with a Live Task
Use the newly created CLI to give the speaker a specific task, such as fetching information from the web and displaying it.
Example prompt
Use the CLI again to tell our audience about the most recent episode of How I AI.
Step05
Observe the Result
Watch as the AI executes the command, uses the CLI to fetch the requested information, and streams a message and animated graphics directly to the speaker's screen.
