Button definition

Start: Start the button, after the countdown is over, press this button to start the counter Begin counting down. Reset: When this key is pressed, no matter what working state it is working in, the counter will immediately reset to the preset value of 24 seconds. Pause: When this button is kept pressed, the counter pauses counting. After the button is released, the timing continues. Reminder: If the buzzer is quiet or does not sound, you can directly use the cut pins to short-circuit and solder R7. The display may be messy after power-on, just press the reset button.

Welding tips

Pay attention to the positive and negative poles of the power supply, the resistance value should correspond to the one on the board, the chip model is inserted in the corresponding position, and the chip notch direction is all upwards. Both LEDs and electrolytic capacitors have long pins that are positive.
