Hello arduino friends.I create a project for control Air Condition (A/C) from web browser local or from anywhere in the world.For example you can start your home A/C from your office or opposite, before returning from a trip for set up the ideal temperature...I decode my remote control IR signals and create IR library signals.I use an IR led for transmit signal connected at digital pin and a temperature sensor connected at analog pin.You can add and humidity sensor,PIR sensors,Laser sensors,Light sensors (LDR)...Another way is an universal remote control connected with arduino from digital output via transistor as switch with on/off button or other buttons.Also you can add mosfets and relays for other devices without IR signals for example electric infrared heating panels.The user interface is a simple html page inside SD card for show a virtual remote control for A/C.You can send me suggestions and ideas for improvement of the website graphics (virtual remote control image) and extension of the code for controlling other devices.Thanks.

I create an arduino+cellphone project for remote control A/C or other devices with IR signals, with sms or call.
I have photos , videos , explain AT commands and arduino code for communication between phone and arduino.
I connect cellphone with cable or via bluetooth.
You can add pir sensor,temperature sensor,smoke sensor for create alarm system.
The GSM project link is http://www.power7.net/GSM_tutorial.html
Thanks.

Hello arduino friend.You need only receive data from arduino+bluetooth send to android back...Try my bluetooth terminal  https://play.google.com/store/apps/details?id=arduino.bluetooth.terminal work for me i test it with my sketch http://www.power7.net/apk_file/Android_Bluetooth2.ino via serial pins 0,1 send 1 wait...and reply 25...You must put android near shield better...Do you have pair devices with android?Check the cable connection Tx,Rx....

Hello arduino friends.I have create many applications for arduino and android.
For example you can control your arduino from web browser,or with sms,or with simple call or with android timer...with android as mobile modem
via bluetooth or usb connection.
I have upload my android apps for arduino to Google Play Android Market.Thanks.

Yes.I create an android application for control arduino with USB shield . My apk is IO Web Usb and the link is https://play.google.com/store/apps/details?id=ioweb.usb .This apk convert android to modem for arduino.
In the future i will create tutorial and explain code!

Yes arduino friend with my applications or projects you can do it!!!You can add and android camera!!!

Do not spam.I just want to present my hard work for my android apps for arduino projects!

Connect your bt dongle to pc , open BlueSoleil and scan for supported services...If you find serial service , you can open it and convert it for your arduino project.Another solution is to connect with usb shield and arduino.But better buy a bluetooth shield for arduino.I suggest HC-07 work very well for me.

I create many android applications for control your arduino via bluetooth or usb from web,sms,call.For example with IO Web Bluetooth apk you can control from web browser your arduino with android as modem https://play.google.com/store/apps/details?id=io.webbt.More infos visit my site for all my projects.

Your bt dongel support serial connection service?

Οkay.I will be more careful next time about links.

I create Detect call Bluetooth , an android application for receive incoming call from another cellphone and send via bluetooth to arduino or other device with bluetooth serial connection service.With this application android converted to modem for control devices with incoming call or you can use for show the incoming call to LCD screen for example handsfree incoming call viewer for car,motorcycle,bike,home project or you can connect heart with red leds for look incoming call from your girlfriend.You need connect a bluetooth shield with arduino and pair with your android.If you load the sketch from my site www.power7.net and setup admin number , android send "1" and the led of your arduno must turn on.You can download it from Google Play Android Market https://play.google.com/store/apps/details?id=detect.call.bluetooth

It is possible but you must create java application for old cellphones or if you find something from internet...

Yes arduino friend this is possible with android smartphone , Bluetooth shield ,arduino and LCD screen. I create an android application https://play.google.com/store/apps/details?id=io.sms.bt  IO sms Bluetooth when receive sms send to arduino bluetooth.I created for bike riders another application Detect call Bluetooth.Look inside my site www.power7.net

I test it again and work....i load my sketch from arduino 0022 software new Arduino software not accept serial,BYTE....without external power supply.
I upload my serial monitor... and video  youtube.... to my site www.power7.net ...look.
