Press S2 once ,one hour will be added. Press the S1 once, one minute will be added, the seconds value
can not be changed. When the hour value is more than 23, it will display --： --： -- which stands for
closing the alarm function.
④Countdown Function:It displays O and the colon part goes out after press S3 three times for a short
time. Press the S2 to choose the hour,minute and seconds, press the S1 to increase the value of the
hour, minutes. The sixth time we press the S2, it will start to countdown, press the S2 again to stop
countdown and we can choose the function again.
⑤Stopwatch function:Press the S3 fourth for a short time, it displays 00：00：00, the colon part lights.
Press the S2, it will start to count the second, press the S2 again, it will stop counting and we can reset
the stopwatch at this time by pressing S1.
⑥ Counter function: Press the S3 fifth in a short time, it displays 00：00：00, the colon part goes out,
Press the S2 to add the value with one, press the S1 to reset the counter.

The Icstation 6 Digit Electronic Digital Alarm Clock is a DIY assemble kit designed for users to build their own digital alarm clock. This device offers a range of time-keeping and utility functions, making it a versatile tool for various applications beyond just telling time.

Function Description

The core function of this device is to display time, which it does in a clear, six-digit format. Beyond basic time display, it incorporates several other modes accessible through its three control buttons: S1, S2, and S3. S3 serves as the primary function selection key, S2 expands the functionality within a chosen mode, and S1 is used for incrementing values.

The device operates in six distinct modes, which can be cycled through by pressing S3 for a short duration (less than 1 second). If S3 is pressed for a longer duration (more than 2 seconds), the device will revert to displaying the current time.

1. Clock Function: Upon powering on, the device defaults to displaying the current time, initially set to 10:10:00. This is the primary time-telling mode.

2. Correct Time Function: To adjust the time, users can enter this mode by pressing S3 once. In this mode, the current time and the colon separator will flash, indicating that the time can be edited. S2 is used to increment the hour value, while S1 increments the minute value. The seconds value cannot be directly changed in this mode.

3. Alarm Function: Pressing S3 twice consecutively enters the alarm setting mode. The display will show 22:10:00 by default, and the colon separator will remain lit. Similar to time correction, S2 increments the hour value, and S1 increments the minute value. The seconds value for the alarm cannot be adjusted. A unique feature of this mode is the ability to disable the alarm: if the hour value is set beyond 23 (e.g., 24, which wraps around), the display will show "--:--:--", indicating that the alarm function is turned off.

4. Countdown Function: This mode is accessed by pressing S3 three times. Initially, the display shows "O" and the colon separator is off. In this mode, S2 is used to select whether to adjust hours, minutes, or seconds. S1 is then used to increase the value of the selected time unit. After setting the desired countdown duration, pressing S2 a sixth time will initiate the countdown. Pressing S2 again during an active countdown will pause it, allowing the user to re-enter the function selection.

5. Stopwatch Function: Pressing S3 four times enters the stopwatch mode. The display will show 00:00:00, and the colon separator will be lit. Pressing S2 will start the stopwatch, counting seconds. Pressing S2 again will pause the stopwatch. While paused, S1 can be pressed to reset the stopwatch to 00:00:00.

6. Counter Function: The final mode, accessed by pressing S3 five times, is the counter function. The display shows 00:00:00, and the colon separator is off. In this mode, S2 increments the displayed value by one with each press. S1 is used to reset the counter back to 00:00:00.

Usage Features

The device is designed as a DIY kit, meaning users are responsible for assembling it. This hands-on approach provides an educational experience in electronics. Once assembled correctly, the device is ready for use.

• Power Requirements: The device operates on a DC voltage range of 7V to 12V, with 9V being the most commonly used and recommended voltage. Users must pay careful attention to polarity when connecting the power supply to avoid damage.
• Intuitive Control: The three-button interface (S1, S2, S3) is designed for straightforward navigation and adjustment across all functions. The consistent use of S3 for mode selection, S2 for function expansion/start/pause, and S1 for value increment/reset simplifies operation.
• Visual Feedback: The flashing colon in the "Correct Time" mode and the lit colon in "Alarm" and "Stopwatch" modes provide clear visual cues about the current operational state, enhancing user experience. The "Countdown" and "Counter" modes have the colon off, further differentiating their states.
• Alarm Disablement: The ability to disable the alarm by setting the hour beyond 23 is a practical feature, preventing unwanted alarms without having to completely reconfigure the alarm time.

Maintenance Features

As an electronic kit, maintenance primarily revolves around proper assembly and handling.

• Soldering Quality: The performance of the module is highly dependent on the quality of soldering during assembly. Ensuring all components are correctly soldered is crucial for reliable operation.
• Power Polarity: Strict adherence to power polarity (DC 7V-12V, typically 9V) is a key maintenance aspect to prevent damage to the circuit. Incorrect polarity can lead to component failure.
• Component Replacement: In the event of a malfunction, the DIY nature of the kit means individual components can potentially be replaced if they are identified as faulty, assuming the user has the necessary skills and tools.
• Environmental Considerations: Like most electronic devices, it should be kept in a dry environment and protected from extreme temperatures to ensure longevity. The "REMOVE SEAL AFTER WASHING" label on the PCB suggests that the board might undergo a cleaning process post-assembly, and the seal should be removed afterward for proper operation or to prevent residue buildup.
