How to Send Your Raspberry Pi Data to Arduino Cloud

Step-by-Step Tutorial: Sending Raspberry Pi Data to Arduino Cloud

Prerequisites:

• Raspberry Pi with an operating system (Debian Bullseye used in this tutorial)
• Access to Raspberry Pi documentation for setup assistance

Step 1: Create a Manual Device on Arduino Cloud

1. Head over to the Arduino Cloud and create a new "thing."
2. Define variables like "button," "led," and "test value" that will be linked to the Raspberry Pi.

Step 2: Set Up Raspberry Pi

1. Ensure your Raspberry Pi is running an operating system (e.g., Debian Bullseye).
2. Install necessary dependencies by opening a terminal window on the Raspberry Pi:
   • Install Arduino IoT Cloud package using pip install ardino iot Cloud.
   • Install Swig package using pip install Swig.
   • Install the gpiod library for using pi gpios by running the appropriate command.

Step 3: Create the Script on Raspberry Pi

1. Connect an LED and a button to the Raspberry Pi for demonstration.
2. Create a script that controls the LED, reads from the button, and sends random values to the Arduino Cloud every 10 seconds.
3. At the top of the script, fill in the credentials (secret key and device ID) generated when creating a manual device on Arduino Cloud.

Step 4: Launch the Application

1. Run the Python script on the Raspberry Pi.
2. Monitor the Arduino Cloud dashboard to observe changes.
3. Test the functionality by interacting with the virtual switch on the cloud dashboard to control the LED connected to the Raspberry Pi.

Step 5: Project Scaling and Bonus Feature

1. Consider scaling up your project for more sophisticated automations by adding more components and functionalities.
2. Explore the variable synchronization feature to synchronize variables on your Raspberry Pi with an Arduino board without additional networking code.

Conclusion:

• By following these steps, you have successfully connected your Raspberry Pi to the Arduino Cloud, demonstrating a basic project setup. You can now expand and enhance your project further for more advanced applications.

Additional Notes:

• For detailed assistance on setting up the Raspberry Pi itself, refer to the Raspberry Pi documentation.
• Experiment with different components and functionalities to customize your project according to your requirements.
• Enjoy exploring the possibilities of integrating Raspberry Pi with the Arduino Cloud for various IoT projects.
