Building IoT projects with AWS Lambda and AWS Greengrass

Integrating AWS Lambda and AWS Greengrass can leverage your IoT business. In this section, we will explore IoT projects to implement AWS Lambda and AWS Greengrass. We will build a simple app to monitor a local resource, such as a sensor.

Accessing local resources

AWS Greengrass can access local resources. This is possible if we use AWS Greengrass version 1.3.0 or later versions. You can configure an AWS Lambda to access specific resources. The following is a list of local resources that you can apply:

• Folders and files
• Serial ports
• USB
• GPIOs
• GPUs
• Cameras

To show you how to work with local resources in the AWS Greengrass Core machine, we will access local GPIO resources...
