On August 26th, from Noon to 4pm, we're going to cover software on the Arduino.
This is different from other workshops we've done on Arduino. Â We'll cover the IDE, built-in Libraries, their uses and pitfalls. Â We'll go over the current Arduino sheild ecosystem, investigate embedded C best-practices, and more!
This workshop will be strictly BYOA (bring your own Arduino), and will run about 4 hours. Â Feel free to stick around afterwards to ask any questions we didn't cover. Â Buy your Arduino from Radioshack, Sparkfun, or any number of other online vendors. Â Bring your laptop and a USB cable, and we'll make the Arduino sing.
Here's a detailed list of topics covered:
What is a Microcontroller?
What training wheels does Arduino provide?
What are sheilds?
What are libraries?
Getting into the IDE
Blinkenlights
Built-in Peripherals
Pitfalls
Basic embedded C techniques
Going beyond Arduino
If there's any particular topic you'd like to dive deep into, email me at BradLuyster@gmail.com
February Freeduino Frenzy is a workshop that will happen on Feb 13, 2011. It will consist of several experiments that will teach the student how to do basic circuits and coding on the Freeduino (Arduino) platform. Some of the projects will closely follow the Spring Training from the Spring of '10, some of the projects are brand new! Sign up and lean valuable skill on how to use and program your Freeduino.
You will need to bring a laptop and a Freeduino or Arduino or clone. Do not sign up if you do not have a laptop or Freeduino! You will need the laptop to program the Freeduino.
If you can, please download and install the Arduino Programming Software on your laptop as described here. That would save some time.
BTW - this is called a Frenzy because I know I have too much stuff packed into an afternoon. All of my instructions will remain online so you can revisit them whenever you want. I hope we will make it through everything - but no promises.
Learn soldering and basic Arduino programming in this workshop. The cost of this workshop also covers the materials cost for a freeduino microcontroller kit. Your assembled Freeduino is yours to keep! Use the vast open resources of the Arduino community to come up with your own electronic applications. This workshop is intended to teach you necessary skills for further exploration in the world of Arduino.
We had a fantastic weekend at LVL1. Not only was LVL1 at an awesome Actors Theater event, we also had some important visitors at the space on Saturday! On Saturday, Mitch Altman (of TV-B-Gone fame) and Jimmy Rodgers (of LOLshield fame) presented a soldering workshop. There must have been 50 people around! Also Matt Mets and Dale Dougherty were here from Make Magazine. Big thanks to Mitch, Jimmy, Matt and Dale for being part of the LVL1 experience. Our doors are always open to you!
During the soldering workshop, I built at LOLShield. Nice kit - lots of LEDs to solder. Jimmy was really good at making his LEDs come out in neat little rows - mine, not so much. Here is my video
I came upon this post and decided to make an animated LOLShield LVL1 logo. I had to download python 2.6 and the PIL library and the script ran perfectly. I created an animated gif using Gimp. Set up an image to be 9X14 in grayscale. Then draw your picture (zoomed in) and animate it using multiple layers. When you save as a gif, Gimp will make the layers into a animated gif. It is not hard. Here is my gif...
It is tiny! Next run the script in the command line and then cut and paste the code. Here is the Arduino program I am using.

Basic LoL Shield Test

This needs the Charliplexing library, which you can get at the

The BitMap array is what contains the frame data. Each line is one full frame.
Since each number is 16 bits, we can easily fit all 14 LEDs per row into it.
The number is calculated by adding up all the bits, starting with lowest on
the left of each row. 18000 was chosen as the kill number, so make sure that
is at the end of the matrix, or the program will continue to read into memory.
Here PROGMEM is called, which stores the array into ROM, which leaves us
with our RAM. You cannot change the array during run-time, only when you
upload to the Arduino. You will need to pull it out of ROM, which is covered
below. If you want it to stay in RAM, just delete PROGMEM

I had to adjust the code to keep it from blinking at the end of the animation.
