AVR thermometer with Nokia 3310 LCD

This is pretty classic temperature sensor project that uses Atmega8 to read thermistor data via ADC channel. Temperature is displayed on Nokia 3310 LCD display with a nice graphical indication.

In order to drive 3310 LCD there is a ICC Darmini’s library used with slight modifications enabling updating single pixels without refreshing screen. Additionally thermometer periodically sends temperature data via USART that could be captured by PC or other device.
