- Voice Command: type words like LIGHT ON — when you say them, the app sends their data.
- Hand Gesture: show ✋ or ✊ to the camera — each gesture sends its data.
- Test button in Code Mode: try it without sending anything.
💡 Tip
Voice needs Chrome and internet. Camera widgets ask for camera permission the first time.
🚀 Your turn
Make an app where saying FAN ON and FAN OFF sends F and f.
