Re: Unofficial Sensor Board (PicoBoard) FAQ

I think I'll get one for Christmas. This should have more than one page by now!


Oops, nvm. I just made a 2nd page.

Right....ultimate power...uh huh.  No, I'm not sure why, I can sticky on other parts of the forum, but not on the Sensor Board area.  Another of life's mysteries!

wow.. this is getting really off topic...

Re: Unofficial Sensor Board (PicoBoard) FAQ

Dear Chalkmarrow,
I am a middle school technology teacher using Picoboards with my 7th grade students. We would like to use the slider function in a game of Pong where the handle is moved by moving the slider. We are having problems because the slider does not seem to go to the  negative numbers on the screen, therefore only covering half the playing board. Not ideal as you can imagine. Can you please help? Any assistance would be most appreciated.
Sincerely,

Re: Unofficial Sensor Board (PicoBoard) FAQ

msz123:

What you want to do is "map" the values from the slider to the Y screen value, which will be a linear sort of thing where you multiply the slider output by some constant, then _substract_ some other constant. The subtraction part is key to getting the negative values. I"ll take a look at the slider output again and see if I can give you a better idea of what to do.

If I'm correct, the slider outputs a number from 0-100, correct? So for controlling the handle, I would firstly subtract 50, so the values could only be from -50 to 50. Then, I would multiply it by 4.8, so the range would increase from -240 to 240. Like this:

[blocks]
<set x to(  ((  ((  <{  slider value  }>   <-> 50  ))   <*> 4.8  ))
[/blocks]

Kind of rough looking, but I think that should work.

Re: Unofficial Sensor Board (PicoBoard) FAQ

I figured out a problem with PicoBoards. You can't have multiple projects using the PicoBoard open in Scratch at once, otherwise only the project first opened works.

Do we have a complete Programming Code for the Scratch board especially the serial communication part? links given seems to be broken.

Sure! But it'd take some electronics know how. Probably easier to just buy one from sparkfun.

There is an assembly kit named NanoBoard. (karenb has one.)
It's 1500 yen ($20). Over 20 kids successfully soldered it in Japan.
If you're interested in it, I can support to export it.

Re: Unofficial Sensor Board (PicoBoard) FAQ

I have some scratch boards which I got a long time ago, which were working fine until I upgraded to 10.7 on my macbookpro. Now, I can't get scratch to show any sensor board readings. When I try to select the serial port I am able to select /dev/cu.usbserial; however, the drivers I downloaded from prolific say that it should be /dev/tty.usbserial.
The latter is what is listed in the Terminal.

How do I do this? I fel there is something I'm not doing!

I really want to use the scratch boards for my projects with kids I work with. Any help is greatly appreciated.

I have also tried the FTDI serial usb drivers and none seem to work.

Thanks in advance.
