This instructable is the written version of my "Arduino : How To Control Stepper Motor via Bluetooth (with Smartphone)"

In this project we will control a Stepper motor with a smartphone via bluetooth.

First, you should see the following Instructable:

How to Control a Stepper Motor With L293D Motor Driver

Step 1: Tutorial

The Stepper motor used here is a rusty old EPOCH (5 wires) stepper motor, which is a unipolar stepper.

Step 2: Parts Required :

Parts Required :

- Bluetooth Module ( for example : HC05 or HC06 )

- Jumper Cables

Step 3: Circuit & Connections

Bluetooth Modul VCC to Arduino 5V

(at the same time if you want, you can use 3V3)

Bluetooth Modul GND to Arduino GND

Bluetooth Modul RX to Arduino TX

Bluetooth Modul TX to Arduino RX

Step 4: Programming

Get the Code and Application

*** When uploading code remove the Bluetooth VCC cable

Step 5: Create Application

I use "App Inventor" for create application

MIT App Inventor

Step 6: If I Was Helpful

<p>Thank you so much for posting this. </p>
<p>can you use iPhone?</p>
<p>Mert kardeş tebrik ederim, g&uuml;zel bir &ccedil;alışma olmuş. Burada bizlerden birilerinin &ccedil;alışma yaptığını g&ouml;rmek g&uuml;zel.</p>
<p>Yorumun i&ccedil;in teşekk&uuml;r ederim.</p>
<p>if you are using a 5 volt based arduino you need the following. if using a 3.3 volt based arduino you need the following</p>
<p>Thank you for the information. However, some manufacturers of Bluetooth module sets the voltage range. As I like my use. My advice is to use all of 3.3V.</p>
<p>If you are running something like a pro-mini running on 3.3v, there is no issue, but most Arduino boards are 5.0v. I looked at a several HC-0x boards I have here, and they all say, &quot;Level 3.3v. Power:3.6 - 6v.&quot; So using 5v to power them, is not an issue. In addition sending 3.3v as a high signal from the HC-0x to the Arduino is also not a problem. The problem is the sending the 5v signal from the Arduino to the HC-0x. Early on I had a problem with *some* boards. The problem was solved by adding a voltage divider...which is just two resistors correctly placed. </p>
<p>Note, I've had problems with some HC-5 and HC-6 modules wired in the configuration you specify. The issue is a 5v Arduino txd signal being received by the HC-x 3.3v rxd pin. A couple of resistors used as a voltage divider to bring the voltage down to 3.3v fixed the problem for me.</p>
<p>I agree with your opinion.</p>
<p>This looks great! I'll try to do it tomorrow.</p>
