Arduino Night 2

Agenda: 1. Transistors for LEDs and motors (a repeat, but really important!) 2. Shift registers to control LEDs (and possibly 7 segment displays) 3. Using tactile switches (including de-bouncing) 4. Talking to other Arduinos

If you would like a shift register of your own, please let me know. I ordered 10 for the last class and will happily part with them for a $1 donation to the space. For those of you who would like to order one prior to the class, the part number is 74HC595. Available from Jameco, Mouser, DigiKey, Adafruit, and SparkFun. I am fairly certain that we have several at the space as well.

Since the space runs off of donations, we would like to mention that the recommended donation for this class is $10. It is by no means a requirement! Attendance to the space and this class is, as usual, 100% free to all! And a huge thank you to those of you who donated last time!
