Project 43 – Temperature SD Datalogger

Now you'll add some DS18B20 temperature sensors to the circuit along with a DS1307 RTC (Real Time Clock) chip. The readings from the temperature sensors will be logged onto the SD Card, and you'll use the RTC chip to read the date and time so that the sensor readings and the file modification can all be time stamped.
