Re: Raspberry PI - analog sensors with Arduino

[Rabin Yasharzadehe]

אין מידע טכני על הערכה עצמה (יש רק רשימה של המודולים), אבל ממה שאני רואה
מהתמונה השניה מדובר ברכיבים שמורכבים על לוחות PCB שיש לו פינים שאמורים להקל
עליך לחבר את ה"מודול" לתוך מטריצה מחוררת
 ואז אתה
רק צריך לגשר מה-BOARD של ה-RPI לתבנית.

שים לב גם שה-RPI לא אמור לתת לך הרבה זרם ביציאה של הפינים , אז אל תנסה
להשתמש בו כדי לדחוף התקנים טובענים שצורכים הרבה זרם (ממסרים , מנועים וכ"ד)
אחרת זה יהרוס לך את היציאות של ה-RPI (בשביל למתג דברים כאלה אתה תצתרך סוג
של דוחף זרם\טרנזיסטור)

-- 
בגדול נראה לי שהערכה תעבוד ,
מהתעוד של ה-GPIO של ה-RPI אני רואה שהוא עובד על מתחים של 5V ו-3.3, שזה אמור
להספיק לך לרוב הדברים שאני רואה שם בערכה בלי בעיה.
אבל כדי להיות בטוח הייתי מבקש מהספק שישלח לך DATASHEET פרטני יותר של כל
הרכיבים שיש שם בערכה.

Re: Raspberry PI - analog sensors with Arduino

[Shlomo Solomon]

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.

Re: Raspberry PI - analog sensors with Arduino

[Rabin Yasharzadehe]

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.

Re: Raspberry PI - analog sensors with Arduino

[Shlomo Solomon]

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

Re: Raspberry PI - analog sensors with Arduino

[Kobi Zamir]

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:

Arduino is probably the easiest / cheapest way to access analog sensors.
While quality of these do vary, I have had good experience with these very
cheap units. Note that you need to program these devices via a USB cable
and an FTDI programmer (you can also find one on ebay for a few dollars). I
would recommend for someone new to Arduino that you get an Arduino uno /
sparkfun redboard (or a chinese clone of one of these) - they have the
programmer built into the board (so you just plug it via USB to your
computer). They also have headers soldered onto the board already, so you
can connect sensors, LEDs, etc without soldering, which is good for getting
started.

Raspberry PI - analog sensors with Arduino

[Shlomo Solomon]

I hope this is not OT - and if it is - sorry.

I recently started "playing" with controlling simple devices using the
PI GPIO pins - trivial things like controlling a LED or servo.

I want to experiment with some analog sensors - temperature, magnetic,
etc. There are several kits available, but from comments I've read
about most of them, they are not "really" meant for the PI and the best
way to use them is to connect the PI to an Arduino.

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?
