Simple USB temperature probe
It is based on Atmel AVR ATtiny45 microcontroller and AVR USB library, also from Objective Development. The temperature sensor used here is LM34 which is an analog precision integrated-circuit temperature sensor, whose output voltage is linearly proportional to the Fahrenheit temperature. There is also a Celsius version LM35 that can be used instead. Source code and schematics is available for download on the project page.
