Beginners Video Tutorial Series for IoT With Intel Edison ( IntelIot)




Introduction: Beginners Video Tutorial Series for IoT With Intel Edison ( IntelIot)

About: Software Innovator, RealSense Trailblazer, Hardware hacker,

About a month back I had the opportunity to be part of IoT road show being organized by Intel in Pune, India. It was an amazing experience. I wanted to build an IoT controlled RC car with few features. Having worked with Arduino, getting started was easy. But rest was difficult. Constant loss of WiFi signal and not so deep knowledge about the techniques in IoT technologies did not help me to create a great demo. Though I completed the demo and won best video presentation and a Basis Peak watch from Intel, the experience was hardly satisfactory. I wanted more. After coming back from Pune, I started digging down various technologies and options with Edison.

I realized that though there are several isolated tutorials in Edison, a complete learner series is missing. Where to start, what to start, what next to learn was difficult. So I decided to document my learning as part of videos.

The idea was that I must have enough resources so that if anybody tries to get started, he wouldn't have to spend that much time in internet. As a personal choice I find video tutorials to be more complete than web articles ( just my personal preference).

So I have created several how to do guides in Intel Edison along with some simple projects. As my process of learning has just began, I expect to learn more and therefore this Instructables would be updated as and when I learn anything new on Intel Edison.

If might just help someone looking for some basic insights and easy learning process.

Step 1: Getting Started With Arduino IDE in Intel Edison

In this tutorial we shall also learn the basics of Grove modules, what the pins are and how to use them. This is more of quick start feel good tutorial.

Step 2: Tip to Make Arduino Sketch Run at Startup

Edison does not start your Arduino sketch automatically. After you upload the sketch, it is basically a executable which is saved in /sketch/sketch.elf . Each time you reboot, you need to manually run this file. With following workaround you can run the sketch from start.

create a file by name


then paste following content

#!/bin/sh exec /sketch/sketch.elf

/dev/ttygc0 /dev/ttygc0

:esc wq enter

mv / /etc/init.d/

/ at the end is imp

chmod +x /etc/init.d/

update-rc.d defaults

That's all reboot and each time you start edison, Arduino sketch will start automatically.

Step 3: Adding Input to Your Control. LED and Button

This is another Basic tutorial with Simple Hardware. Here I have tried to elaborate coding logic for input driven control. How to make control decision based on state of buttons.

Step 4: Mini Project: Temperature Display in LCD and Alarm System

Previous two tutorials were extremely basic foundations. Having learnt some Arduino programming basics and hardware, we will now put that knowledge into creating a simple high temperature alarm system. In the process we will also learn how to find external libraries for your hardware, working with I2C and LCD basics.

Step 5: IoT With Edison: WiFi, Curl, ThingSpeak and Data Logging

So far we have got ourselves comfortable with hardware and Arduino programming. But We did not configure our device to Internet. In this tutorial we learn how to connect Edison to internet, how to login to the device from multiple putty windows using WiFi, how to use command line remote http calls using curl. We then extend this to make a simple data logging project where we log the data in sdcard and as well as in ThingSpeak.

Step 6: MQTT

MQTT is a light weight Machine to Machine communication protocol that makes remote control and simple data exchange efficient. You can control devices through web, windows, Mobile and everywhere.

We conclude this tutorial with a simple Mini project where we control LED with our mobile.

Step 7: Setting Up Node Red

Node Red is a visual programming tool by IBM. This makes your IoT programming extremely easy with drag and drop nodes. This is a javascript based interface. However working with all the capabilities need some more packages. This is just an installation guide for node red and other associated modules you need to start with node red programming.

Step 8: Node Red Programming a Complete Walkthrough

In this tutorial I have tried to cover all important building blocks in node-red tool. Input, output, GPIO, functions, Social integration.

We have transmitted our data to Gmail and Twitter, written processing blocks to consume command from twitter.

As a mini project, we have controlled On-Board LED from Twitter.Analog read and thresholding is another aspect which is covered here.

Step 9: Working With Bluetooth in Edison From Node Red and Node.js

Will Upload video Soon!

1) Unblock Bluetooth:

rfkill unblock bluetooth

2) Login to Bluetooth Console bluetoothctl

3) Make discoverable discoverable on

4) scan the device: scan on

5) once the device is seen in list, ctrl+c

6) pair

7) connect

8) trust

9) Download Android bluetooth SPP app

10) Now we need to follow an Intel Tutorial Here:==>

a) download :

b) using WinScp to upload the file to /home/root

c) untar the package

mkdir /home/root/bluetooth

cd /home/root/bluetooth

mv /home/root/bluetooth-service.tar.gz ./

tar -xvf bluetooth-service.tar.gz

d) Prepare for Bluetooth at startup

cp bluetooth-spp-pin.service /lib/systemd/system

e) systemctl enable bluetooth-spp-pin

f) reboot

g) after login back:

systemctl status bluetooth-spp-pin

11) This package has a file by name which runs serial port service and release them in a named pipe: /tmp/arduino_pipe_out So now we need to write a bash script that can read from this named pipe 12)




trap "rm -f $pipe" EXIT

if [[ ! -p $pipe ]]; then mkfifo $pipe fi

while true do if read line <$pipe; then

if [[ "$line" == 'quit' ]]; then

break fi

echo $line

fi done

echo "Reader exiting"

13) Make it Executable

chmod 755

14) ./

It will now wait for a bluetooth command. From your app, generate bluetooth command You will see that is appearing in the command prompt

15) javascript does not support pipes. So we need to release it using websocket

16) Download websocketd a command based websocket deamon

17) Unzip. copy the file websocketd to /home/root

18) chmod 755 websocketd

19) run the deamon ./websocketd --port=8080 ./

20) Now go to your node red from input take websocket

Type: Listen On

Path: /ws://localhost:8080

20) Connect it to debugger ie it.!!!

    you may have wrong youtube URL for both step 4 and 5, they are the same about Node red configuration


    6 years ago

    Try to install node-red, keeping getting this "-sh: node-red: command not found"

    any idea

    That is more beatiful code, I think

    It is really nice, TY!
