Hello world !
This was the first program i wrote a several years ago. From then i started exploring different fields of application of programs and their existence in our real life. A few days back some guy come to me and asked " do you know about IOT" ?? I was like !!
IOT --Internet of things , Big thing huh ! ....
So I am here now to explain you about a little bit IOT and a lots of funny and relational things we can do actually with it in real life . Lets get started
What is IOT ??
In my words : Its all about connecting your lill things around your daily life with internet , and getting some important data from it .
How its going to affect our life??
Ans: Just imagine you forgot to water your plants on weekdays . On Monday in office you suddenly remembered that you forgot to water them ... Then What ?? you will come to home and water them ?? I don't think so !! Where IOT comes into picture , By just programming one Arduino like module and interfacing some Sensor and Actuator , you can water your plant sitting at your office and lots more .............
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Required Hardware +Software
- Arduino +ethernet Shield or cc3200 Dev board
- 1x100 ohm register
- 1xRGB LED
- 1xEthernet Cable
- One laptop with Arduino IDE
- Wifi for CC3200 and Ethernet for Arduino
Our Ultimate outcome will be to control LED from a web Interface , means communication between Arduino and your laptop . Where my Website will act as a middle ware server for your communication
Software libraries we will be using for arduino are MQTT client lib ...
can be downloaded from here DOWNLOAD ARDUINO MQTT CLIENT
Just install the library as normal arduino library installation
Step 2: Website
Go to this website IOT SERVER
Follow the Pictures to help yourself
First register and then verify through Email
Then login ...... You will be redirected to your Dashboard for LED Toggling
Step 3: After Log In
After you logged in to my server successfully Click GET API DETAILS
Write Down your API Details somewhere safe , Dont Share with anyone
Now go to the drop-down HARDWARE
Then select Arduino +Ethernet shield Or for CC3200 select cc3200
Then You will be redirected to the download page , Download the appropriate file according to your Hardware .
Copy the code.....................................................
Step 4: Getting Into Hardware
Paste the code you downloaded from the Website into your IDE , in our case ARDUINO IDE or ENERGIA IDE
Then just Put Your API key <YOUR API KEY HERE> in the code
Find it in the Code .......
Just upload it to appropriate device ARDUINO or CC3200
and then move back to YOUR DASHBOARD from where you selected your HARDWARE
Step 5: Finally
Now Starts the fun part .... MAKE you connected RGB Common anode to ground , and ARDUINO PIN 7,8,9 will be connected to R,G,B terminals of the LED .
Make sure your WIFI password and SSID is filled in the Energia code .
Make sure you have an active internet connection and Arduino with Ethernet shield is connected to an active internet connection
Now in DASHBOARD you can see this two buttons
Press the CONNECT BUTTON first VERY IMPORTANT STEP
Then press the PRESS ME Button to initiate connection between arduino and your dashboard interface
If everything goes right ...... You can see the LED STATE is Changing if you toggle the WEB LED switches ..... TRY it if problem persists I am here Your friend KANKAN Thanks .
