One thing my project arm does is determine the end-effector's maximum and minimum heights and radii on startup. The servos driving the arm may be attached at arbitrary angles (they can even slip a bit after being attached) and their limits can...

Hi Susan. The SD card module does not have a name that I can see, but I don't think it does anything except level shift between 3.3V and 5V as SD cards support SPI natively. It is connected to the ICSP header on the RedBoard, leaving out the reset...

Hi Tyler. How did you add the SD card to the Arduino? As a chip on the breadboard? As a shield? What is the SD card called? Thank you.

In an effort to avoid the XY-problem, I'll first describe my entire goal: I'm attempting to locate objects placed within a boundary by scanning the area with a moving sonar sensor, with the final goal of automatically picking them up with the...

Good points, Gerald. It is indeed a lot to do with controlling pedagogies. And, like so many such studies, these looked at average effects but, to the best of my knowledge, I have never met an average student.

Thanks, Tim, I might do that. Noise was already being smoothed with a rolling average (100-point), but it wasn't enough and averaging so many points was causing problems of its own. My next step would be circuit isolation from heater and some RC...

The Verge reports on a variety of studies that show taking notes with laptops during lectures results in decreased learning when compared with notes taken using pen and paper. This tells me three things, none of which is what the article is aiming...

  Jon,
  I am so glad you responded to this article. It has been festering under my skin all week and I haven't had the chance to blog about it (yet).
  I completely agree with the issue primarily being a structural one about teaching and learning instituions. It also strikes me that (not surprisingly) it is about control on the part of the instructor (or fear of loss of control).
  The other component missing is the idea that learners are individuals with individual needs and motivations.
  Cheers.

With the amount of noise that's evident just in the proportional case, it's no surprise that derivative action didn't work out. If you want to spend more time on it, getting everything synchronized should help a lot with any periodic noise...
