Hi Guys, I was recently introduced to this group, so here is my first post.
I work/volunteer at the Southend Technology Center in Boston. We teach technology to kids and adults fostering interest in technology for kids and enabling adults to be more competitive in the workforce. We were the original Fab Lab initiated by MIT, and continue to have a strong relationship with MIT. We have laser cutters, shopbot, broken 3D printer, and teach kids to work with arduino. I manage the computer hardware repair workshop. So I have taken on a project (over my head) using old computer parts and raspberry Pi. I am trying to build a POV sign that can gather data from the net/cloud/remotely. I have followed this example http://www.skpang.co.uk/blog/archives/454 to get LEDs controlled by a raspberry. But now like to convert this to using this http://adafruit.com/products/459 a bi-color 12 bar led (for more colors and cleaner product) I figured out the wiring to get the bar to light up using the same codes as above. So I am now ready to control the LED bar, and that is where I am stuck...on the python code to control the I2C. I think my too basic knowledge of electronics and programming would be benefited by someones help. This is my immediate challenge to figure out how to program the I2C for the LED bar, then eventually, I need to program a python code to POV display the messages which i can imaging that it get pretty challenging given how to form a character with LED while timing the rotation. So I am looking for someone who maybe familiar with I2C to offer insight and hopefully someone that has time to tinker on this project along with me. I am at the tech center typically in the afternoons till 8PM at 359 Columbus Ave in the Southend. So any help through email or in person would be greatly appreciated. Thanks Ming
