Use DC5.5*2.1 power port with 3V – 6V power supply, come along with a 3.5mm USB power cable, plug in the USB charger to use, easier to get the power supply support.
Schematic as below picture.
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.
Installation Steps:
Step 1: Install 2pcs Resistor, 3pcs ceramic capacitor, 1pcs Crystal Oscillator.
Step 2: Install 1pcs Network Resistor. Pay attention to the installation direction.
Step 3: Install the IC Socket. But pay attention to the installation direction.
Step 4: Install the 2pcs button. But pay attention to the installation direction. Install 1pcs S8850.
Step 5: Install 1pcs Power socket; 1pcs Electrolytic Capacitor; 1pcs Buzzer.
Step 6: Install 4Bit Digital Tube and IC. And then test!
