This is a little DIY project with an Arduino Uno, SD card breakout board, and LM35 temperature sensor. To build a temperature logger using a microSD card, just connect the LM35 analog temperature ...

A few days ago, one of [Severin]’s SD cards died on him, Instead of trashing the card, he decided to investigate what was actually wrong with the card and ended up recovering most of the data… ...

// open the file. note that only one file can be open at a time, // so you have to close this one before opening another. myFile = SD.open("test.txt", FILE_WRITE ...

He was inspired by Intel’s Edison compute module and he tried to go one better. The result is the SDuino, an ATMega328P processor-based development module, which fits on a standard SD card. It even ...

Framework says it’s breaking tradition by “pre-announcing” a full-size SD card module that may never ship but could potentially fulfill a long-standing community request.

When the clone starts up, it searches the SD card for a file called ‘program.hex.’ This file is sent over to the target Arduino and the new firmware is installed.
