Create a Kid-summoning IoT Device with Spark OS

This article explores the Spark Core, a Wi-Fi enabled Arduino, and its application in creating simple Internet of Things (IoT) devices. It details building a "kid-summoner," a device that sends a tweet when a button is pressed, using the Spark Core, Pushingbox, and a Twitter account. The tutorial covers setup, wiring, coding, and deployment, emphasizing the cloud-based coding and remote updating capabilities of the Spark Core. Furthermore, the article suggests extensions to the project, such as adding variable messages, location data, multiple buttons, and motion sensors. Finally, it includes a FAQ section addressing common questions about IoT device creation, security, and maintenance.

Key Features of the Spark Core:

• Wi-Fi Connectivity: Enables seamless integration with the internet.
• Cloud-Based Coding: Simplifies development and allows for remote updates.
• Integrated Breadboard: Streamlines prototyping and simplifies wiring.
• Versatile Applications: Suitable for a wide range of sensor-based projects.

Creating the Kid-Summoner:

The "kid-summoner" project uses a simple push-button to trigger a tweet via Pushingbox. The steps involve:

1. Pushingbox Setup: Create a scenario to send a pre-defined tweet to your child's Twitter account.
2. Spark Core Configuration: Connect the Spark Core to your Wi-Fi network using the Spark mobile app or CLI.
3. Circuitry: Wire a push-button and resistor to the Spark Core according to the provided diagram.
4. Coding: Write and upload the code to the Spark Core using the Spark web IDE. This code reads the button's state and sends a request to Pushingbox when pressed.
5. Testing: Test the functionality by pressing the button and verifying the tweet is sent.

Expanding the Project:

The basic "kid-summoner" can be enhanced by:

• Customizable Messages: Incorporate variables into the tweet for dynamic content.
• Location Awareness: Add GPS coordinates to specify the summoning location.
• Multiple Buttons: Implement multiple buttons for different messages or actions.
• Motion Sensors: Integrate motion sensors for alternative triggering mechanisms.

Frequently Asked Questions (FAQs):

The article concludes with a comprehensive FAQ section covering various aspects of IoT device development, including security, troubleshooting, software updates, power optimization, and data utilization. This section provides valuable insights for both beginners and experienced developers. The inclusion of external resources like Fritzing and Make Magazine further enhances the article's value.
