Since class was cancelled last week, I will have the same slides ready for this week. If not enough people show up, then I will do the same class again on the 7th. So don’t fret if you can’t make it 🙂
We will be using 7 segment displays. Two new topics will be covered: sinking current and C arrays.
If you have your own 7 segment, feel free to bring it. There will be several to choose from if you need one.
Agenda:
1. What is a 7 segement
2. Explain sinking of current
3. Determine type of 7 segment
4. Wire up to Arduino
5. Write code to display a single number
6. Change code to flash a number
7. Change code to show two numbers
8. Introduction to arrays in C
9. Use an array to count with the 7 segment
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 (6:45-7:00 PM).
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
Provided Items:
1. Breadboard and jumpers (if you don’t have any of either)
2. Resistors (200 – 500 Ohm)
3. 7 segment display
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!
