• Use Google Cloud IoT
• Build a simple dashboard

4. Build a Real Project 💡 Choose one:

• Smart room temperature monitor
• Home automation system
• Environmental sensor network
• Simple security system

Long Term (Next 3 Months)

5. Production-Ready Systems 🏭

• Handle many devices
• Implement proper security
• Add monitoring and alerts
• Scale your infrastructure

6. Specialize 🎯

• Edge computing and local processing
• Advanced protocols (CoAP, WebSocket)
• Time-series databases
• Real-time dashboards

Mini Projects to Try

Put your knowledge into practice:

1. Add Humidity to the Payload

• Modify the JSON message to include humidity
• Update the device code to read from a humidity sensor
• Display it on the dashboard

2. Add a Fan Control

• Add a “fan_on” boolean to your messages
• When temperature goes above 25°C, set it to true
• Display this on the dashboard

3. Simulate Two Rooms

• Create two devices (room-101 and room-102)
• Send temperature from both
• Update the dashboard to show both rooms side by side

4. Add Retry Logic

• Implement retry with backoff in your device code
• Test it by temporarily disabling the network

5. Build a Simple Dashboard

• Create a basic web page that displays temperature over time
• Use a simple charting library like Chart.js
