This document provides instructions on how to get started with Node-RED for connecting Arduino to the internet. It explains that Node-RED is a visual tool for wiring hardware, APIs and online services. It then provides step-by-step instructions on installing Node-RED, adding serial and social media nodes to send sensor data to Twitter, ThingSpeak and IBM Watson. It also includes shortcodes for installing common Node-RED nodes like for Google Charts, MySQL and Alexa.

17. Installing thingspeak node
Step 1 Stop the node-red running server by closing it or by
“stop node-red” or by ctrl+C
Step 2 Use “npm install node-red-contrib-thingspeak” to install
thingspeak node
Step 3 Start node-red server, you will find thingspeak node in
functions at the end of the list
Step 4 Visiting thingspeak.com and signup for an account
Step 5 Create a channel and get Write API Key

18. Flow 2: Uploading sensor data on ThingSpeak
Step 1 Drag and drop serial input node to flow dashboard
Step 2 Double click to configure it and select com port & baudrate
Step 3 Drag and drop thingspeak node from function
Step 4 Double click the node to configure it, enter your write API
Key, Don’t forget to enter the field id as “1”
Step 5 Connect both the nodes
Step 6 Deploy the project by clicking on the top right button Deploy
Step 7 Check your private view in your thingspeak channel

19. Installing IBM Watson IoT node
Step 1 Stop the node-red running server by closing it or
by “stop node-red” or by ctrl+C
Step 2 Use “npm install node-red-contrib-ibm-watson-
iot” to install IBM Watson IoT node
Step 3 Start node-red server, you will find IBM Watson
IoT node in Input & Output list at the end of the list

20. Flow 3: Uploading sensor data on IBM Watson IoT
Step 1 Drag and drop serial input node to flow dashboard
Step 2 Double click to configure it and select com port & baudrate
Step 3 Drag and drop IBM Watson IoT node from function
Step 4 Double click the node to configure it, select quickstart mode,
click on the edit symbol(pencil) next to it to get the dashboard.
Step 5 Connect both the nodes
Step 6 Deploy the project by clicking on the top right button Deploy
Step 7 Check your on the IBM Watson iot dashboard opened.
