Teacher Notes

Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.

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

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.

This looks great! I'll try to do it tomorrow.
