Per a request at the last class, we will be writing to and reading from SD cards.

Please bring an SD card if you can. There will only be two available for use!!! Also, the cards must be SD, not the smaller cards. All cards should be 8GB or less and be formatted to FAT16 or FAT32. Larger sizes might work, but I haven’t tested it.

Agenda:

1. Look over the LC Studio breakout boards
2. Interfacing with SD cards
3. Resistor dividers
4. Wiring up the breakout board
5. Run demo code
6. Create custom code to write ADC samples and then read them back

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
7. Variable resistor (potentiometer) for setting the contrast
8. SD card if you have one. Preferably <= 4GB

Provided Items:

1. LC Studio SD card breakout 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!
