Arduino/Android- 28BYJ 48 Stepper Motor Control Using the HC-06

Hello world! Today i made a simple app to turn one 28BYJ 48 stepper motor on and off, it just rotates to one direction. I will make a app to control the curtains of your house next, with the same motor. If you want the source code of the android app just ask! I will ask a very small favor in return. Go to the next step for the Schematic, Parts list & code.

Just wire it up like the Schematic and it should work after uploading the code.

Make sure you disconnect the HC-06 when uploading the code. Other wise the arduino becomes confused.

Parts list.

1. Arduino uno, I used the RobotDyn Uno which has 7 analog pins instead of 5.
2. HC-06 Bluetooth module.
3. 28BYJ 48 Stepper motor With the ULN2003 driver board
4. Jumper wire set. MM/FF/MF
5. Android phone and our APP.

Get the APP on GOOGLE PLAY

Good luck!

To find out how to rename your HC-06 & set PIN + change baud rate. Follow step 2 (optional)

What is needed?

1 x USB to TTL microcontroller programmer to connect to your HC-06

How to connect the Programmer?

VCC to VCC

GND to GND

RXD to TX

TXD to RX

Lets get started...

1. connect the USB TTL programmer to the HC-06
2. Plug in the USB and open up The Arduino IDE
3. Open the serial monitor.
4. Type "AT" without quotes. You should see a respond in the Serial monitor saying "OK"
5. Type "AT+NAMExyz" Sets the module name to “xyz” (Replace xyz with the name you want.) response should be OKsetname.
6. Type "AT+PIN1234" Sets the pin to 1234 (replace 1234 with your desired pin) respond should be OKsetPIN For more info on changing baudrate etc. i included a PDF file. Good luck!
