If you are looking to start with the Internet of Things, then try out the Arduino MKR1000 and connect it to the ThingSpeak IoT Platform. We have put together a complete tutorial that uses the MKR1000 to collect data about your Wi-Fi signal and send it to ThingSpeak for storage, analysis, and visualization.
The Arduino MKR1000 is a great starting point when learning about the “things” in IoT. The MKR1000 has a microcontroller, Wi-Fi module, encryption module, and a battery-charging circuit. It’s easy to get started and once you get it connected to ThingSpeak, you have a lot of “cloud power”. ThingSpeak has a suite of apps to allow the Arduino to post messages to Twitter, do data analysis, show charts and visualizations, and be controlled by schedules and external events. With these building blocks you can prototype any IoT system.
