Thanks to you but can you make one for fetching timetable from sd Card and display on going sessions on lcd at particular time

Hello Sir!
How should i read the last line of my sd card data while using ardunio

[vikaskumarsinha]

I got this error even after following you :
Initializing SD card...initialization failed. Things to check:
* is a card inserted?
* is your wiring correct?
* did you change the chip-select pin to match your shield or module?

Dear Sir. Can you help me, please?

I need to know, how to open(read) a file without need to wrote the file name on the skecthe.

For example, in my SD card, I have a txt file with any name. I want to open this file, regardless of the filename, only by the file extension. I am trying to build a hardware, that writes binary files to an EEPROM chip. If I don't get this, I will have to keep renaming the files on the sketch for each different file I want to write to memory.

will arduino suppourt 16/32 gb sd cards iam trying its two days but always showing sd card intialization failed
i tried with esp8266 also there also showing same error .. id ont have 4gb or 2 gb sdcards...connnections jumpers are correct

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.
