Learn how to use the simple SparkFun AT42QT1010 and AT42QT1011 capacitive touch breakout boards.
  • Yeah, you're making some great points! I especially like the idea of some kind of cue before the lights turn out. I had considered keeping count on one of our mini-OLED screens or better yet the transparent OLED.... https://www.sparkfun.com/products/15173 ....but I would have to be on the wrong side of the tripwires to check that the count went to zero. The audible cue on the other hand is smart AND fun. A Mario coin sound every time someone enters the room and the Mario tunnel sound when the last person leaves, neat! I also like how you expanded on the PIR sensor that the other user suggested. Thanks for the thoughtful post =).

  • hahaha =P

  • It'll also tell me if my dogs are in my office....not a bad idea.

  • I've seen coworkers waving their arms like you mentioned because the PIR sensor doesn't sense them in their office. I worried about the same thing with this project which is how I settled on counting individuals. I'm too committed at this point to go back to a PIR sensor I think.

  • Yes I agree and for a moment I did look into it, but had some difficulty finding the low level pin assignments. Let's use Atmel chips as an example because I'm more familiar their datasheets. Where do you find the pin assignments for PORTB or access the timers, TCCx for example? I had trouble finding them in the Arduino folder structure.

    I'm not using lenses but I am looking at how to focus their beam. I am just considering some PVC pipe at the moment. You guessed right, they will only be shooting 3-4 feet.

    I thought about range sensors, but didn't want to over engineer the project. IR LEDs seemed simple enough in design and in code. Have you had success tracking a number of people and their direction using them?

  • He died 100 years too early =/ https://en.wikipedia.org/wiki/Alexander_Stepanovich_Popov

  • Agreed completely, I'll be working on Micro Python next™. I'm not entirely sure on their justification there, except that they probably wanted to determine which areas were developed themselves. /shrug. Just as a note, I didn't add a link to the repo, since its linked in the "Documents" tab above.

    (Looks like that TM mark isn't rendered)

  • Hello again! I was very mistaken in my last comment: it is indeed possible to do upload a UF2 bootloader and Circuit or Micro Python. I went ahead and added a UF2 build as well as a Circiut Python build to the SAMD21 Mini Github repo under the Firmware folder.

  • I just spoke with one or our interns, and she's on the case! I can't give any specific times as parts need to be ordered and build times vary. TLDR, they will be coming back in stock.

  • You're not the first person who requested a part number. Unfortunately the supplier of that part does not sell them in small quantities. =(
