AVR Switch Timer using ATmega8 Microcontroller




To get better UV expose, Andrianakis has built new Switch Timer that will turn of his UV exposure box after some time. The timer uses ATmega8 as main processor and two 7-segments LED as display. There are two buttons for set and start the timer. When time runs out, microcontroller switches relay and also sounds a buzzer.

The time is calculated by timer interrupt triggering using a 32.768 KHz RTC Crystal with better accuracy. The firmware is written in C and you can compile it using WinAVR.
