How to make a connection between an internet service and Arduino boards.

In this project, we’ll Learn how to make a connection between an internet service and Arduino boards. At the end of this article, you will:

know how to get data from Google Assistant
know how to use IFTTT protocol
be familiar to webhooks and http requests
be able to speak to your Arduino

This tutorial will help you to send SMS to any registered mobile number from ESP8266.

Concept behind the Tutorial:

We know that the ESP8266 module can be configured both as AP or STA. Here we have configured it to work as station and have connected it to our Wifi Router. Once the connection is establish we have to find out a way to send SMS online. This online must also be easily accessible by out ESP8266 module. This is where we leverage the power of IFTTT (If This Then That) website. Using this website we can send SMS, E-mail, Whatsapp messages, Facebook updates, Twitter tweets and what not. They have a heck a lot of tools that can be used with little knowledge, but in this tutorial we are going to use the send message feature and leave the rest for other future tutorials.

After few tweaks in the IFTTT website we will able to get a HTTPS URL which when triggered will send a predefined Text message to a specific mobile number. Now, this URL has to be called by our ESP8266 module when needed and your SMS will be fired to your mobile number. Sounds fairly simple right!!? Let us see the steps involved.

I fell in love with the sound of a grandfather’s clock. But it was too expensive for me. And that clock has no alarm and snooze option. And it knows nothing about my emails or text messages.

So I bought the mechanism of a used grandfather’s clock on. It has a simple structure: The chime rods tinkle, when the hammers hit, when the solenoids pull in, when the Raspberry Pi sets voltage on the GPIOs, when the IFTTT webpage calls the Raspberry Pi’s webserver, when I receive an important email.

Raspberry Pi 3

For all the DIYers, tinkerers, and creative coders out there — we’re thrilled to introduce you to the Maker Channel.

The Maker Channel extends the power of IFTTT to any DIY project, big or small. You can now build and connect Recipes to any device or service that can make or receive a web request.

From creating browser extensions to connecting a Raspberry Pi or Arduino with Twitter — it is all possible with Maker.

The Maker Channel allows you to connect IFTTT to your personal DIY projects. With Maker, you can connect a Recipe to any device or service that can make or receive a web request (aka webhooks). See how others are using the Maker Channel, or share your own experience at hackster.io.

The Internet of Things is getting to be a big business. Google’s Nest brand is part of the trend, and they’re building a product line that fills niches and looks good doing it, including the Nest Protect smoke and CO detector. It’s nice to get texts and emails if your smoke alarm goes off, but if you’d rather not spend $99USD for the privilege, take a look at this $10 DIY smoke alarm interface.

The secret to keeping the cost of [Team SimpleIOThings’] interface at a minimum is leveraging both the dirt-cheap ESP8266 platform and the functionality available on If This Then That. And to keep the circuit as simple and universal as possible, the ESP2866 dev board is interfaced to an existing smoke detector with a simple microphone sensor.

$10 DIY Wifi Smoke Alarm Notifier (Roost & Nest Alternative) (Full Tutorial)

However with the emergence of IoT devices, now there are some cool products on the market right now that will send you a smartphone notification when your smoke detector goes off.

Nest Smoke Alarm + Carbon Monoxide Monitor ($99, Nov 2015) – A replacement for the traditional smoke alarm that sends an alert to your phone when it detects smoke.

Roost Smoke Detector Smart Battery ($40, Nov 2015) – 9V Battery you can install in any traditional smoke detector, which will notify you via a smartphone app if your alarm is going off. Battery lasts for 5 years, at which point the non-smart portion of the device needs replacement.

These look like great devices, but for some consumers they will be too expensive. Especially if you need multiple devices, it starts to get very expensive very fast. What if I told you you could build yourself a simple sound sensor that sends you a smartphone notification, SMS, and even call your phone when your current smoke detector rings. You could also build this for about $10 bucks. If that sounds interesting to you, read on!

I know you’ve seen these types of tutorials on the internet before, and usually they say something like, just buy a breadboard, soldering iron, breakout board, serial adapter, etc. etc. and after you’ve spent about $50 dollars you can build a cheap Internet of Things (IoT) device. Well, sorry internet. We nerds sometimes forget that most people don’t really have these things lying around. That’s why I built this website around the idea that IoT devices can be built without coding knowledge, soldering, or complicated prototyping.

One of the reasons why IoT devices can be built so easily now is because of the ESP8266 development board. IoT enthusiasts have been excited about the ESP8266 because its a full system on a chip (SoC) that has onboard wifi connectivity that can cost as low as 3 dollars. The IoT community has been building with Raspberry Pi and Arduino microcomputers for a while now, and while capable these computers cost up to $35 dollars, don’t have onboard wifi, and aren’t easily powered with common ports like microusb. The standalone ESP8266 chip is great, but doesn’t have an easy to use power supply and it’s hard to configure without special cables.

To make building IoT devices both easy and cheap, I recommend using the ESP8266 development board.

The Wifi Smoke Alarm Notifier, and all of the projects on SimpleIOThings use an internet service called If This Then That (IFTTT). IFTTT executes an action, like sending an SMS or posting a Tweet, when an event takes place.

Using the Maker Channel

For SimpleIOThings projects we’re going to use IFTTT recipes that use the Maker Channel. The Maker Channel allows people to create recipes that interact with DIY devices. The DIY devices you can build using tutorials from SimpleIOThings will send messages over the internet to the IFTTT Maker Channel, which then triggers actions like phone calls and SMS messages. The Maker Channel can also send messages to DIY devices to trigger actions on the device as well.

Once you connect to the Maker Channel, take note of your “Maker Key,” which is an alphanumeric code that identifies you and your DIY devices when they send web messages. You can jot it down somewhere, or you can always go back to https://ifttt.com/maker to find it.
