Summary of AVR digital clock with white seven segment LED display using ATtiny26 microcontroller
This project is a digital clock using an ATtiny26 microcontroller to drive four bright white seven-segment LED displays. The display shows time in hh.mm format by default, with an option to switch to mm.ss. Time setting is controlled via two push button switches. The clock multiplexes the seven-segment LEDs through PORTB, with the segments controlled by PORTA pins.
Parts used in the ATtiny26-based Digital Clock:
- ATtiny26 microcontroller
- Four seven-segment LED displays (bright white)
- Two push button switches
- Resistors (for current limiting)
- Connecting wires
- Power supply (battery or regulated DC source)
This is a digital clock project based on an ATtiny26 microcontroller, displaying time on four seven segment LEDs. The seven segment LEDs glow bright white and are multiplexed through PORTB pins, whereas the segments are driven by PORTA pins. The time is normally shown in hh.mm format but it can be switched to display mm.ss too. The time setting can be done with two push button switches.
