Understanding Digital Clocks

The video explores how digital clocks function, starting with the power source, which can be a battery or a plug with a transformer. It explains the 'heartbeat' of the clock, generated by a crystal oscillator or electrical oscillations, measured in Hertz. The clock counts these oscillations to keep time, using a chip to divide them into seconds, minutes, and hours. Finally, the video describes how the display works, showing time based on the counted oscillations. The video concludes with acknowledgments to supporters.
