2. AWS Account

3. AWS CLI https://docs.aws.amazon.com/cli/latest/userguide/installing.html

4. AWS Credentials attached in the computer https://docs.aws.amazon.com/cli/latest/userguide/cli-chap-getting-started.html

Create serverless.yml in ./server. Use the template provided serverless.tmpl.yml. Don't forget to change the custom variables.

Deploy the application using sls deploy

1. Go to AWS AppSync, create a project and start with the schema in schema.graphql placed in this repo.

2. Connect the mutation and query with the dynamodb table which is created later by the serverless framework

Designed using Raspberry Pi 3 model B & Raspberry Pi sense hat. Make sure you install the prerequisites in your raspberry pi.

2. pip install influxdb

3. start influxdb sudo service influxdb start or you can make it auto start on reboot using sudo update-rc.d influxdb defaults

4. Create influxdb user and database. you can go to the admin page at {your raspberry ip address}:8083. Note that the port may not always be 8083. Please check if you cannot use port 8083

5. pip install AWSIoTMQTTClient

6. pip install SenseHat

7. Create your device in AWS IoT Core. use this guide https://docs.aws.amazon.com/iot/latest/developerguide/iot-sdk-setup.html
