|ATtiny85 controlling sewable neopixels|
At the time I was working on this project, there was still one step that required the use of a PC: the process of burning a boot loader/ changing the fuse timing on the ATtiny85. To use neopixels, the ATtiny85 needs to run on an 8 Mhz internal clock, rather than the default of 1 Mhz. As of 11 January 2016, this issue has been fixed, making it incredibly easy to do this type of thing with students using Chromebooks!
Once I converted the chip to 8 Mhz, I was able to use CodeBender and a Chromebook to program it with neopixel sample code (with only a couple of small tweaks).
My next step was to see if I could apply this new learning to building a paper circuit with copper tape and surface mounted RGB LEDs. The photos demonstrate a prototype using the surface mounted RGB LEDs soldered to wire!
Since I was able to get the LEDs to do what I wanted with wire, I am 100% convinced that this can be replicated with copper tape! Stay tuned!
