LM35 & Memory Card. 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 ...

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.
