Principle

The whole system by MCU minimum system, key input circuit, display circuit, buzzer circuit, and power supply parts.
1>. MCU minimum system: including the U1 (STC11F02E), C1, R1 for power-on reset circuit. The clock circuit is composed of C2, C3, and Y1.
2>. The pressed key input circuit: composed of S1, S2, short press the button once a loud buzzer rang, long-press the button once two loud buzzers rang.
3>. The display circuit: 4bits common cathode and on PR1 Resisters Packs.
4>. Buzzer circuit: composed of Q1, R2, and LS1, short press the button once a loud buzzer rang, long-press the button once two loud buzzers rang.
5>. J1 is a 5v power supply input terminal, C4 filtering.
Notice please: there is the direction for PR1 Resisters Packs, there is one side of the word in the direction of the MCU.
