That's the project I've made with the help of Kerimil.
Take a look below! you can download everything at my website:

I'll add a new example app soon - I still have to film it. Support for sliders has recently been added so I just want to show you how to use them to control RGB lights (and how to send several values using send string and parse int on arduino side)

ohh and if you have any suggestions or ideas for apps feel free to post them - I am running out of ideas  smiley

Thanks Kerimil!
I finished my project a few days ago... (you can watch it here: http://randomnerdtutorials.com/arduino-control-2-dc-motors-via-bluetooth/)

And by the way, please read the P.P.S.

Thanks again for your awesome help!

Good job   smiley-cool

Thanks Pedro!

A few days ago I've made an LED Cube tutorial. It's really easy to make one and I show exactly how you can do that too in a few minutes..
I've create also two video the first one is the tutorial. The second one is simply the Demo.
You can download all the arduino code for free on my website. (I didn't made this code, this is the LED Cube library)

You can download all the schematics and the arduino for free here: http://randomnerdtutorials.com/arduino-led-cube-3x3x3/
Thanks so much for reading I hope you find this information useful!
All the best,

thanks!
Actually I made my app work 2 days ago before I saw your answer . I don't know why I didn't figured out that before it was pretty easy bug to fix ... smiley
thanks for your help (yeah that was my mistake: " the problem was that your app was sending bytes and arduino was expecting integers")

All the best,
Rui Santos

I've just tried that ... It's still not working :s
Its working fine with blueterm app... but when I try with the app inventor app it connects fine to my bluetooth module but when i press the buttons nothing happens...

do you have a better idea for me to debugg this code?

thanks so much for answering!

Hi kerimil.
First I would like to say thanks so much for sharing your work!
I would love if you could help me...
I'm working on a project similar to a previous project I've made a few months ago (you can visit my website to check my project http://randomnerdtutorials.com/arduino-control-dc-motor-via-bluetooth/)

In my previous project I was controlling one DC motor... But now instead of controlling one DC motor I want to control 2 DC motors... my code is working perfectly when I'm using the BlueTerm app for android. (BlueTerm app is similar to putty it sends information to my arduino via bluetooth....) And my circuit is pretty much the same as the one i've showed on my website... I just added another motor... My circuit is working perfectly because it works with the serial monitor (when i send 1,2,3,4,5... and when I send via blueterm app those numbers)

And I want to create an App to send that same information to my arduino but with MIT App Inventor...
here is my arduino code: http://randomnerdtutorials.com/wp-content/uploads/2013/08/sketch_aug29a.zip
here is my Mit App Inventor code: http://randomnerdtutorials.com/wp-content/uploads/2013/08/blue.zip

I've tried to replicate your code to my project but It's not working. (I'm using HC-05 Bluetooth Module)
I can't find out my problem and I've searched a lot...

My app connects fine to my bluetooth module but when I click forward, left ... nothing happens.
So It's a problem with my app... somethings is missing...

Could you please take a look at my code and project?
And try to help me out I would be really thankful! I want to share this project with my friends on randomnerdtutorials and of course I will give you credit for helping me out!!

Thanks again and best regards,
Rui Santos

P.S. I would like that my app looks similar to this: http://randomnerdtutorials.com/wp-content/uploads/2013/08/d.png
8  Using Arduino / LEDs and Multiplexing / Re: Temperature Displayed on 4 Digit 7 segment (common anode) on: April 28, 2013, 07:02:19 am
Very nice project!  My original inspiration in buying an Arduino was to create a thermostat for temperature in a house.  Output current temperature, allow input through maybe an Android cell phone to adjust temperature and automatic shut off when that temperature is reached.  Something very similar to the NEST thermostat system seen here:

http://www.nest.com

Except not as pretty.
Thanks!
yeah that's an interesting project I already saw some similar projects and they are really useful!
9  Using Arduino / LEDs and Multiplexing / Temperature Displayed on 4 Digit 7 segment (common anode) on: April 19, 2013, 04:06:41 am
This was a really quick project I've made recently, a simple 4 digit 7 segment common anode that displays the room temperature:
you can find the code and schematics for free here:

Also you can check the circuit in action :

10  Using Arduino / Motors, Mechanics, and Power / Control DC Motor via Bluetooth (Tutorial) on: February 24, 2013, 04:37:36 pm
Hi guys,
In this project I controlled a DC motor with a smartphone via bluetooth. This project is great to learn more about:
    -DC motors
    -Interfacing Arduino with your smartphone
    -Bluetooth
    -L293D IC

You can check the circuit in action in this video and all the detailed information plus all the code in my website:
http://randomnerdtutorials.com/arduino-control-dc-motor-via-bluetooth/



Leave me some feedback if you enjoyed this project!
Thanks for reading!
11  Using Arduino / Interfacing w/ Software on the Computer / Re: Control Servo with Visual Basic on: February 14, 2013, 09:04:14 am
I see two possible improvements:
- let the visual basic program specify an arbitrary angle instead of just a character which maps to a predefined set of angles;
- have a "set" command which the VB program would use to make the motor run to a specified angle, and a "get" which would return the angle of the last "set" command (in simpler words: "set" motor position, "get" current motor position).

Just my 2 cents... smiley

yeah that can be easily done and it's a good idea, I might try do that soon or something similar as you said for a pan tilt with a camera. So I can control the camera to rotate for wherever I want.
currently I’m finishing 3 projects
I’ve also formatted windows 7 yesterday and installed ubuntu so i don't have visual basic at the moment.
Thanks again for your advice I really appreciate !
12  Using Arduino / Interfacing w/ Software on the Computer / Control Servo with Visual Basic on: February 12, 2013, 04:16:31 pm
Hi,
I'm not sure if this is the right place to post this project.
Anyway I'll share my latest project... Arduino with Visual Basic
You can check all the info (like all the code) on my website and see in the youtube video the circuit in action!

http://randomnerdtutorials.com/arduino-control-servo-with-visual-basic/

I don't know why but youtube cropped my video, the Last two buttons are "Rotate 180º Left" and "Rotate 180º right" .



thanks for reading, give me some feedback!
and any improvement to my code post on my website or something.

14  Using Arduino / LEDs and Multiplexing / Re: Control LED's with a remote control on: February 10, 2013, 05:34:54 pm
Thanks for sharing. Nice and simple wiring, and the demo shows how easy it all is.

Would be interesting to know the range of the remote. smiley
yeah that would be a good idea to show or to try, but unfortunately I didn't remember that, i've tried at least 2 meters away and it worked... so i guess i could be a bit more far!
I've already started another project and i've took all the circuit apart but it's really easy to wire so probably tomorrow i will see how far I can be.

Well done, thats cool.

So nice to see a newbie post :-

How do I make a remote change an LED  ?

thanks so much for your feedback!
i'm a newbie with the Arduino but with programming in C and Python i have much more experience,I've decided to post and share all my projects.
I'll be posting more stuff soon.
