I want to read first line of text file from sd card and delete it . After that second line other lines should be shifted .Please help me in logic and commands
Hi i am currently stuck. Everything is working fine but i am unable to get to the Usb drive to do the formatting. The Folder did not pop Up. What should i do? I've worked with 2 sd card and i am having the same problem for both.
Hey Anthony, can you help me? I keep getting the initialization error that the card isn't even recognized... I'm using what looks to be the same SD card reader, Arduino Uno, and a 2 GB Sandisk Micro SD card (same size as yours). I followed the same formatting procedure, as well as your example sketch. I have also tried many other examples and have gotten the same issue. Do you know what my problem might be? Thanks
You can't "clean" data by deletion or formatting. Do not use Windows or other OS formatting to format SD cards. SDcards have several formats and partition types that you can't see/charge easy in Windows and other Format tools. May seem to work but many SDcard problems often resulting in lost data are cause by using wrong formatting. Windows or Mac use SDFormatter from SD Association at www.sdcard.org/downloads/formatter_4/ Correctly handles all cards and options to clean or wipe data by overwriting in software or hardware. That Chip you ignored is a buffer (74LVC125A) used as a level shifter because SDcards are 3.3v devices. Modules without level protection can damage SDcards connected directly to 5v SPI pins.
me gusto su video y bien explicado pero déjeme plantearle algo a ver si usted me ayuda o le sirve como pie para un video nuevo.Yo descargué el software JINX, vay usted ha oodo hablar de este software,con el se hacen animaciones que luego se guardan en una targeta sd,en los videos que yo he visto sobre este software te enseñan hacer las animaciones y como guardarla en una targeta para que luego sea leída por un arduino nano,uno,o mega,pero que pasa que no te hablan del código que debes descargar en el arduino para que te lea las animaciónes que grabaste en la sd y enviarla a una matrix de led.Seria usted tan amable de orientarme donde buscar un código para programar el arduino y este me pueda leer las animaciones que hay en la memoria sd,le repito animaciones que grabe del software JINX.
Looking forward to part two :)
Tomorrow! :-)

Another great video, thank you.
Useful video 👍 Excellent 👍

is there any way to write data as soon as i get it without blocking the pool?
i tried using two arduinos but no luck
Can I use it to read dead SD Card? Soldering directly from the contacts? Do you think its possible?
Hi. I would like to measure of 15 sample of MFC for voltage and current for 40 days continuous . How can i build it?

Hi, try a different card or different reader maybe?

Thanks for your commento!
D11 & D12 of my arduino are already occupied by TFT LCD setup. Can i use other pin instead?
How this is named?
