Arduino Home Automation

Hello
Today i thought i would share with u this project
its fairly easy and dosnt use much parts its the Arduino Home Automation.

Parts needed.
Arduino(any)
Bluetooth module
2 CH Relay
Breadboard
and some jumpers.

Sorry i am demostrating this with LED but Fritzing didnt had any 2 CH rRelay module.
But yeah it works

Arduino Bluetooth
1(TX) RX
0(RX) TX
GRD GRD
5V 5V (VCC)
1 Channel Relay
5V VCC
GRD GRD
Pin 7 IN 1
Pin 8 IN 2

Code for arduino can be found here:http://goo.gl/aOzrYt

Stepper motor driver-Old printer part

Transitor unipolar stepper motor driver

After searching a littl bit in the internet for a simple stepper motor driver all i was finding was
Uln2003 drivers and Easydriver for very tiny motors and my stepper was 2A at 2.6V so i thought i would get and make my own driver.
Now parts that u will need:
1:4 Transistor(I used MJE13007 u can use what ever u want as long as it is more then 2A).
2:4 Diode 1N4001(I didn use any beacuz i am using only 12V but u should if u are using 24V just to protect the transistor).
3:4 Resistor for the base of the transistor.
4:A Arduino

The code for the Arduino:http://adf.ly/qvwjk
You can change the delay until 2 for self start motor
if u change it to 1 you will need to start the motor by hand.
You can experiment with the output of the transistor as not
all stepepr have the same winding.
