The described AVR Digital Clock project utilizes an ATtiny2313 microcontroller as its core component, showcasing a unique approach by displaying time on an oscilloscope rather than traditional visual outputs like LCDs or seven-segment displays. This design choice highlights the versatility of the ATtiny2313, which is a popular microcontroller known for its compact size and efficient performance in embedded systems.

The circuit design includes various passive components such as resistors and capacitors, which are essential for signal conditioning and timing functions. Specifically, the project employs a range of resistors with values including 120 Ohm (R1), 10K Ohm (R4), 100K Ohm (R2, R5, R6, R7, R10), 120K Ohm (R3), 390K Ohm (R8), and 680K Ohm (R9). These resistors are rated at 1/4 watt with a tolerance of 5%, ensuring reliable performance under typical operating conditions.

Capacitors are also integral to the circuit, with two 47 pF ceramic capacitors (C2, C3) and two 100 nF multilayer capacitors (C1, C4) included to manage the timing and stability of the microcontroller's operation. The crystal oscillator (Y1) operates at 4 MHz, providing the necessary clock frequency for accurate timekeeping.

User interaction is facilitated through a tactile switch (SW1), allowing for manual adjustments or settings to be made easily. Additionally, the circuit includes connectors for easy interfacing, such as a 5-pin strip connector (J1) and a 3V clip connector (J2), which enable the connection of power and other peripherals.

The project is well-documented, with source code and schematic diagrams available for download, making it accessible for enthusiasts and engineers looking to replicate or modify the design. This AVR Digital Clock serves as an excellent example of microcontroller applications in timekeeping, utilizing an oscilloscope for real-time display and offering insights into digital electronics design.Usually we see Digital clock on LCD or 7 segmen.
