Actually, since my purpose is to experiment and learn , **getting my hands dirty** with datasheets, etc is OK.
By what you write, I assume you have some experience or knowledge, so I'll ask what I really should have asked in my original post. There are many sensor kits on e-bay, but although some of them mention Raspberry PI, it seems that they are not "really" meant for the PI, but for Arduino. Assuming, I'm willing to **dirty my hands**, do you think they should work on a PI? I'm including a link to a typical kit. http://www.ebay.com/itm/322176545722?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT On Tue, 2 Aug 2016 18:40:05 +0300 Rabin Yasharzadehe <ra...@rabin.io> wrote: > קח בחשבון שיש הבדל מהותי בין שימוש בצ'יפים נטו לבין מודולים מוכנים, > לרוב מודולים יעשו לך את העבודה הקשה של התממשקות עם ה-CHIP וגם קינפוג > ברמת החיווט! > כמו כן גם יחשפו לך את המידע על פרוטוקול סיריאלי פשוט כמו RS232, בלי > שתצתרך להמיר אותו. > > אם אתה לוקח ADC למשל ומנסה להשתמש בו AS-IS אתה צריך לעבור על > ה-DATASHEET שלו כדי להבין כיצד להביא אותו למצב עבודה. > ולהבין כיצד לבצע איתו דגימות וכיצד לתרגם את התשובה שלו לערך עשרוני. > > -- > Rabin > > On 31 July 2016 at 12:37, Shlomo Solomon <shlomo.solo...@gmail.com> > wrote: > > > Thanks to Kobi and Jason. > > > > In the meantime, I've done more research, and I see that there are > > several ADC (analog digital converter) chips available to help the > > PI use analog input. > > Since my main purpose is to learn to use and program the GPIO pins > > on the PI, I guess that would be a good solution - especially since > > my C++ skills are REALLY rusty and I'm much more comfortable with > > Python. > > > > Again - thanks for your replies > > > > > > On Sun, 31 Jul 2016 09:25:31 +0300 > > Kobi Zamir <kobi.za...@gmail.com> wrote: > > > > > Hi, I also think like Json. > > > > > > For the first time you play with an arduino, use a board that has: > > > > > > 1. a usb connector for programming and i/o > > > 2. pre-soldered connectors > > > 3. use standard arduino connector arrangement (like in the arduino > > > uno) > > > > > > For example: > > > > > http://www.ebay.com/itm/UNO-R3-ATmega328P-Development-Board-for-Arduino-Compatible-Free-USB-Cable-/191617917471 > > > > > > > > > > > > On Sun, Jul 31, 2016 at 9:03 AM, Jason Friedman > > > <write.to.ja...@gmail.com> wrote: > > > > > > > > > > > > > > >> I have absolutely no knowledge about the Arduino, but I've seen > > > >> clones advertised on e-bay for less than $2 - link below. > > > >> > > > >> Can anyone tell me if this as actually a working solution and > > > >> if the low price is actually possible? > > > >> > > > >> > > > >> > > > >> > > http://www.ebay.com/itm/1PCS-Pro-Mini-atmega328-5V-16M-Replace-ATmega128-Arduino-Compatible-Nano-/152160908037?hash=item236d7f3305:g:MMcAAOSw2GlXLD~U > > > >> > > > >> > > > > Arduino is probably the easiest / cheapest way to access analog > > > > sensors.
