Learning AWS IoT

Developing local AWS Lambda 

We use Node.js to develop local AWS Lambda. Firstly, we write the Node.js program with the Raspberry Pi environment. Open the Raspberry Pi Terminal and create a folder called blinking. We will use the node-rpio library to access the Raspberry Pi GPIO.  This library can be found at https://github.com/jperkin/node-rpio.

1. Navigate to the blinking folder from the Terminal. Then, we install the node-rpio library by typing the following command:

$ npm install rpio

2. You also need to configure AWS Lambda to enable working with gpiomem. You can do that by typing the following command:

$ sudo cat >/etc/udev/rules.d/20-gpiomem.rules <<EOFSUBSYSTEM=="bcm2835-gpiomem", KERNEL=="gpiomem", GROUP="gpio", MODE="0660"EOF

3. Now, ...
