Internet-based temperature logger with mbed and ThingSpeak

Frank setup a internet-based temperature logger using the ThingSpeak contest data-logging service:

This project uses a mbed microcontroller (LPC1768 ARM Cortex-M3) to monitor temperature using a DS1620 (digital temperature sensor IC), retrieve the time via NTP (network time protocol), and then log the current temperature to ThingSpeak along with a time-stamp.
