The code and electronics we have used throughout this chapter have given us a foundation that we can build upon. This might be to extend your IoTree, or as the basis for other IoT projects.
Here are a few suggestions you can try:
- Add and integrate a PIR sensor that plays an RTTTL tune whenever anyone walks past your IoTree. After all, what electronic Christmas gadget is complete unless it drives everyone crazy by playing tunes over and over and over and over...
- Add and integrate an RGB LED to the top of the tree (maybe inside a transparent star), or use RGB LEDs in place of – or together with – the APA102 LED strip.
- Build multiple IoTrees. If you use MQTT, they'll synchronize!
- Try to build a WebSocket integration and an accompanying web app.
- The current dweet Google Assistant integration requires you to speak commands exactly. Can you create an upgrade that is a little fuzzier – that is, that can...
