This is an update of two articles which I wrote in 2005 about a small digital thermometer. The circuit seems to be very popular because it is so simple and still has a very useful and practical application. It is the perfect circuit to get started with AVR microcontrollers.
This updated article replaces the articles from 2005 and simplifies the software as well as the hardware. The original documents from 2005 are linked at the end of this article in case you still need them.
This thermometer can be used as a standalone thermometer with LCD display or it can be read out with a PC running Linux, Windows, MacOSX or solaris. BSD Unix and others are probably also possible to use for reading the temperatures. No special drivers are needed.
