Arduino Internet (Without Wifi Shield)

About: I'm a high school student like to build stuff, I have a lot to study at school so that's whys you may get late reply's sometimes .

Intro: Arduino Internet (Without Wifi Shield)

In this instructable I'm going to show you how to connect your arduino to the internet, there are many ways to do this. One use an Ethernet shield but its wired and not very convinent to use ,on the second is wifi it may be the best way to connect to internet but wifi shields are expensive its around 80 dollars.
In this I'm going to connect arduino to internet using Bluetooth module and this would cost you around 5 $ . This is the best and cheapest alternative.
If you like my instructable vote for me

Step 1: Requirements

The nessary requirements is a cheap Bluetooth module from eBay HC06 , an android phone with an internet connection. You can buy the cheapest module for 4$ , search over eBay for HC06 . You should use an voltage divider before connecting it to the arduino. Reffer to the circuit for assembly.

Step 2: Android Setup

After you complete the previous steps its time to setup your android . Download an app from play strore named Arduino Bluetooth tether . And set up update time to every 1sec. Pair your android with your HC06 , the pairing code is either 1111 or 1234 . Turn on the app and connect your module.Leave the server URl to default if your using the attached examples or enter your server URL if you want to control your arduino using your own codes.
That's it your done.

Step 3: Example

Then create your own code and server using processing depending on requirements. Visit this 
website for more details and examples-  
Chose a project you like and you'll find the sketch in the description.

    well you will be needing blutooth to comunicate to the internet , you should have some basic knowledge of server comunication. You will be needing two android phones for this. Or a pc and android phone.

    i read in th e playstore description someone who found yr app 'useless' coz there were no setup instructions. You directed him to the website. I checked that.... would you mind saying where on that website it is explained?
    I cant get connection. it does not matter what I fill out instead of HC-07 the connection screen keeps coming back telling me it cant find HC-07. Well maybe that is because I dont have an HC-07 and instructed to search for an HC-06. Onviously the app does not understand that or am i completely missing the point?


    5 years ago on Step 2

    hmm if i fill in th enam eof my device (HC06 or linvor) and press start I get an arreor that it cannot find device HC-07

    so what is the catch?
    I can connect to my bluetooth model with a dongle from my pc and communicate with it, so i know it works

    So is there a way to connect threw a iPhone?


    Reply 5 years ago on Introduction

    ya iam sure if you don't get results search for hc05 or hc07 any one will do. these are the cheapest ones i could find

    hey I did not upload the code . Because there are many to choose from.
    chose your example code from here
