Simple real timer on ATmega16 based on 3 seven segment leds (counting 10 minutes) and 3 controlling buttons (PINB Atmega16). Pinouts of Atmega16 you can see in datasheet_atmega16.pdf or on official page.
- Segment X and Y shows seconds
- Segment Z shows minutes
- Button 0 resets timer
- Button 1 starts timer
- Button 2 pauses timer
Electrical circuit connection of segments:
It's based structure shows how to work with timer in MCU. It can be useful for students class or for DIY stuff who begginer in AVR.
- You can use another MCUs. All you need is datasheet. Don't forget change pins!
- Make project in AVR Studio choosing 8-bit MCU ATmega16.
