Arduino – Control 2 DC Motors Via Bluetooth

only works with AppInventor version 1.0 or also called classic that you can see here http://appinventor.mit.edu/explore/classic.html Click the button: “Invent your own Apps now” . This project still works just fine with my  app and with my Arduino code. But you can only edit the source code on Appinventor classic version. I’ll try to update the source code in the next 4 weeks or something. I’m currently working on another projects that I need to finish right away.
In this tutorial I’ll show you how you can control 2 DC motors via bluetooth with my brand new Android app.thumbdcmotors
It’s called “BlueArd” and It’s the 1.0 version. I want to upgrade my app later and add more features.
This app was created with MIT App Inventor. It’s a great place to start with android development.
If you remember my previous tutorial (Click here to see that project) where I was controlling 1 DC motor, I was using an app called “BlueTerm“. That app did the job but I didn’t like the design that much. So I’ve decided to make my own.
It’s my very first app and It’s working for me but I’m not sure if this will work for everyone.
If you want to make some improvements to my app, feel free to do that. But please contact me here! I’ll be glad to hear what you changed in my app.
Let’s take a look to “BlueArd“:

This app is perfect to control anything via bluetooth. You can edit this app for your needs. (you have the source code below… just click share to unlock the source code). But my idea is to create a robot later that will be controlled via bluetooth through this app.
