This is a timer using a 7-seg I2C-based display, a rotary encoder, a buzzer, and a DS18B20 temp-sensor. The MCU used is an ATtiny84. If timer is not running, the temperature is displayed. The timer is setup using the rotary encoder with push button. During countdown, timer beeps indicate the remaining minutes.
