What is Node-red?

Node-Red in its simplest form is an open source visual editor for wiring the internet of things produced by IBM.

Node-RED is a visual tool for wiring the Internet of Things (IoT).

Node-RED is platform-independent.

Node-RED takes care of the technicalities and lets you concentrate on the logic of your workflow. !

Traditional IoT development can be very technical: Access to the GPIO and other hardware requires skills in C or assembler, output of data to web services or sending tweets and emails requires the use of complex APIs.

While most programming in Node-RED is done visually using pre-defined functions (“nodes”), any additional functionality can be added in JavaScript.

How to Start with Raspberry Pi?

Desktop: Menu->Programming->Node-RED

Visit http://127.0.0.1:1880 in browser and get your dashboard.

Basic Nodes

Flow 1: Twitting sensor dataStep 1 Drag and drop rpi input node to flow dashboard

Step 2 Double click to configure it and select the pin number

Step 3 Drag and drop twitter output node from social

Step 4 Double click the node to configure it, authenticate your twitter account

Step 5 Connect both the nodes

Step 6 Deploy the project by clicking on the top right button Deploy

Step 7 Check your tweets on your twitter account, done by sensor.

Installing Thingspeak NodeStep 1 Stop the node-red running server by closing it or by “stop node-red”

Step 2 Use “sudo 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

Flow 1: Uploading sensor data on thingspeakStep 1 Drag and drop rpi input node to flow dashboard

Step 2 Double click to configure it and select the pin number

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

Flow 1: IBM Watson IoT Demo Step 1 Drag and drop rpi input node to flow dashboard

Step 2 Double click to configure it and select the pin number

Step 3 Use “Sudo npm install node-red-contrib-ibm-watson-iot

” to install the node

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.

Cayenne Cloud by mydevices

Cayenne is the first of its kind drag and drop IoT project builder that empowers developers to quickly create and host their connected device projects.

Cayenne was designed for the Internet of Things.

It can control hardware remotely, it can display sensor data, it can store data, analyze and do many other cool things.

Connecting your Raspberry Pi

1. Signup for a free Account on Cayenne Cloud

2. Once you’re signed up you will need to register/connect the Pi up to the account you just created. To do this simply copy the 2 command lines shown after you sign up. Enter these into the terminal for your Pi. (These files are unique for every new install)

3. It will take a few minutes to install onto your Pi depending on how fast your internet connection is. The web browser or app should automatically update with information on the installation process.

Once installed the dashboard will display and should look like something below.

Controlling LED1. Go to add new in the upper left corner of the dashboard

2. Now search for digital output and select it

3. For this device select your Pi, widget type is button, icon can be whatever you want, and then select integrated GPIO. Finally channel is the pin/channel that our LED is connected to. For this example it is pin #17. (This is the GPIO numbering of the pins)

4. Now press the add sensor button

5. You can now turn the GPIO pin high & low from the dashboard and also use it in a trigger
