Continuing the trend of motor control and transistors, we will be driving bipolar steppers motors. The motors will be provided since having varying stepper motors can be troublesome.

It is suggested to bring a full sized bread board since this will take up a little bit of room!

Agenda:

1. What is a stepper motor
2. Uses of stepper motors
3. How do stepper motors work
4. Wire up using transistors
5. Write code to spin one direction
6. Modify the code to spin both directions
7. Wire up using little driver boards

If you cannot attend the class in person, E-Mail arduino@unallocatedspace.org and ask to be added to the Google Hangout. The hangout will be started just before class (6:45-7:15 PM). If you have not gotten an invite by 7:15 PM, then please E-Mail arduino@unallocatedspace.org.

The slides for the upcoming and previous classes can be found here. The slides are generally made during the three days before a class.

Required Items:

1. An Arduino board of some kind (Uno, Due, Mega, Boarduino, Duemilanove, etc)
2. If your board does not have USB programming built in, you will need a programmer (AVRISP, Bus Pirate, Bus Blaster, AVR Dragon, another Arduino, etc)
3. Breadboard (the long one if possible, though the small square-ish ones are okay for now)
4. USB cable for your board and/or programmer
5. Laptop with the Arduino IDE installed (Linux, Windows, or Mac)
6. Jumper wires for your breadboard (male-male and either female-female or female-male) (these are provided if needed)

Provided Items:

1. 28BYJ-48 stepper motor
2. Simple darlington driver board

Since Unallocated Space runs off of donations, we would like to mention that the recommended donation for this class is $5. It is by no means a requirement, but it does help us keep the lights on! Attendance to the space, and this class, is 100% free to all!
