Two four-digit digital tubes are used as display devices to display the time HH-MM-SS; two independent buttons can set the current time and alarm time; when the alarm time is up, the buzzer will be driven to sound "Beep-Beep-Beep". beep
Detailed explanation of the principle:
The principles of the digital tube electronic clock, button settings and buzzer alarm clock are based on the control of the STC89C52RC microcontroller. The microcontroller realizes the display of the digital tube, the detection of the buttons and the driving of the buzzer through timer interrupt and IO port control.
