3.1. Interactive Function
3.1.1. Voice Recognition
When the device boots up and connects successfully to the Wi-Fi network, the blue LED
light will blink once, indicating that it is ready to accept commands.
Then, you can wake it up with the “Alexa” keyword. When it is woken-up and listening, the
LED light will glow in solid blue. When it is in a “thinking” mode, the LED light will rotate.
We presently support “Tune-In Radio” as a music service. Other music services are not
supported as of yet.
You can interact with the board, using normal free speech. Some examples can be:
•
“Alexa, what is the weather like?”
•
“Alexa, sing a song”
• “Alexa, stop”
•
“Alexa, tell me a joke”
•
“Alexa, play Radio City on ‘Tune-In Radio’ ”
3.1.2. Buttons
The “Vol+” and “Vol-” buttons can be used to adjust the volume of the sound. Press
repeatedly until you reach the desired sound volume.
