it works with all arduino. just connect it to the right SPI pins. SPI pins are listed here on Arduino website www.arduino.cc/reference/en/language/functions/communication/spi/
thank for video very much! How we use again data on SD to put to if function as an example ? I have no way to use data on SD because when I read from SD the data is a strange number while I save a text string
Hi, data on the SD card is saved as pure character. it is up to you however you wan to read it. if you wan tot use it using Arduino, the use C_String to convert it to proper type. you may have a look at this page www.arduino.cc/reference/en/language/variables/data-types/string/functions/c_str/
@@robojax thank for your guide. I try many time, used c_str(). When I save 123, serial.write(myFile.read()) :123 but I have no way to get data on SD by sd.h library, I try to use these codes : String x , x += (string)myFile.read() then my result is number 50, 60 example. Event I saved a text ABC ,my result was still number. Can you help me the way to read data on Sd card again that it like original data as 123 or abc I had save it before. I seem that data is saved on sd is interger type and is coded . Thanks.
Very useful video dear friend I need to use SD card and Arduino as (digital data logger), instead of analog data logger is that possible ? how ? many thanks
Hello... I want to create a table in Excel and save it in the sd card which contains three columns.. The first column is longitude and the second column is latitude and the third column is a number between 0 and 10... then We receive GPS input, and if the longitude and latitude were equal to each of the numbers we wrote in the first column and the second column, it will display one of the numbers (0 to 10) on the serial monitor... Your help is very important to me.
Hello, first you need to learn to write two or three lines in a notepad file and save it as .csv (comma separated value) and then save it. then open it by double clicking on it. It should open in excel and see if data is shown in columns. Or learn from this page www.stats.govt.nz/large-datasets/csv-files-for-download/ download the sample file and open it first in excel so you know how it looks like. then open it using notepad. to open it in notepad, open notepad and open the file. you will learn from it. Learn it my friend it is very easy. You don't need even have to look at anything else, I have shown it in video.
I am very new to these things. I know basic programming. I am working in a project where I need to read 4 different types of data simultaneously using sensors. I have been suggested to use teensy 4.0 as the micro controller for this project due to certain reasons. i need to collect and show the data in real time and also need to program it so that it'll save the data in the SD card in .csv format. I could only understand like 20% of this video. How much should I know so that I can understand the whole video and become useful in the project? January is deadline, please help :(
Hi, to measure simulatinously, you need need to use RTOS library with Arduino or ESP32 which I have no video on that. For understanding the code, you should just watch the video multiple times, if you got questinos, I have over 600 videos and most of them courses. so search my channel or search youTube to get that topic cleared. This is how I would learn.
Hello,I've been trying codding three ir sensor to drive a servo motor if the sensors detects an object at a distance of maybe 50cm but my code is not working at all please help. Regards
These videos are always very well put together, thank you so much for putting in the effort and well put together projects.
very useful video for me . i use sd card and 24 series flash eeprom as storage . thanks ahmad
Спасибо. Видео вовремя. Начал заниматься запись данных . Лайк
Я ценю это. благодарю вас.
very helpful thank you ahmad!
Helpful video 👍
Awesome ❤
Do I need a logic level converter on the Arduino Nano if I have the module without a integrated one?
Thanks, will it work the same with Arduino zero?
it works with all arduino. just connect it to the right SPI pins. SPI pins are listed here on Arduino website www.arduino.cc/reference/en/language/functions/communication/spi/
@@robojax Thanks, Just understood that my MicroSD is too big, maximum for my reader is 2GB

Sd.h 是否考慮增加掃毒功能，否則未來單晶片不知道會不會跟電腦一樣中毒，以上純屬個人觀點
Very useful video dear friend
I need to use
SD card and Arduino as (digital data logger), instead of analog data logger
is that possible ? how ?
many thanks
of course. I gave example and you can use it any way you want.
Data logging stops after getting around 200 data inputs from accelerometer. My wiring is correct. Is there a way to solve the issue ?
hello sir, i was try SD example in arduino lib. is it possible to use sandisk ultra microsdxc 64gb? cz all failed
I mentioned the size of card the video but forgot. See it in video

ohh man.. I see you've even made a video on ESP32 recently, thank you so much once again :D @@robojax

Hello, this video has nothing to do with servo motor. Please post the question under the right video so I look at the code of the video and replay.
How connect sd card to pro micro board
we use SPI pins to connect. List of SPI pins for all boards are shown here www.arduino.cc/reference/en/language/functions/communication/spi/
Hello, when I try to data log it works but after an amount of lines it just clears the data before and has a limit of 500kb please help me
I have not tested to in terms of capacity. The capacity limit should be the size of your micro SD card.
What language is this?
In C language with the exception of added setup() and loop() and other methods and properties defined by arduino. The library is all C.
