3. Assembly Instructions

Follow these steps carefully to assemble your electronic clock kit. Refer to the provided images for visual guidance. A soldering iron, solder, and wire cutters are required.

3.1 Soldering Components to the PCB

Image 3.1: Soldering steps 1-6.

1. Step 1: Install the four 10kΩ resistors. Resistors do not have polarity.
2. Step 2: Install the crystal oscillator. This component does not have polarity.
3. Step 3: Install the ceramic capacitors. These components do not have polarity.
4. Step 4: Install the battery holder. Ensure correct orientation if marked.
5. Step 5: Install the IC holder. Align the notch on the holder with the corresponding notch on the PCB silkscreen.
6. Step 6: Install the buzzer. Pay attention to the positive (+) terminal, aligning it with the marked position on the circuit board.

7. Step 7: Install the transistor. Align the semicircular side of the transistor with the semicircular marking on the circuit board.
8. Step 8: Install the switches (UP, DOWN, SET) and the DC socket.
9. Step 9: Install the photoresistor and thermistor. These components do not have polarity. Leave a distance of approximately 1cm from the circuit board during installation.
10. Step 10: Solder the header pins onto the digital tube display module.
11. Step 11: Check for any soldering errors on the main PCB. Then, install the digital tube display module by inserting its header pins into the corresponding sockets on the main PCB.
12. Step 12: Install the digital tube display module. Ensure it is seated correctly.

3.2 Installing Integrated Circuits (ICs) and Battery

13. Step 13: Install the DS1302 (RTC) and IAP15W413AS (Microcontroller) ICs into their respective sockets. Pay close attention to the notch or dot on the ICs, aligning them with the corresponding markings on the IC sockets.
14. Step 14: Install the CR1220 battery into its holder. Ensure the positive (+) side of the battery faces upwards, aligning with the positive terminal of the holder.

3.3 Final Adjustments and Case Assembly

15. Step 15: Adjust the position of the photoresistor and thermistor so they are exposed and can accurately sense ambient light and temperature.
16. Step 16: Assemble the acrylic case around the completed circuit board. Secure it with the provided screws.

4. Operating Instructions

Once assembled, connect the clock to a 5V USB power source using the provided cable. The clock will power on and display the current time or default display mode.

4.1 Buttons Overview

• SET Button: Enters/exits setting modes, confirms selections.
• UP Button: Increases values, navigates menu options.
• DOWN Button: Decreases values, navigates menu options.

4.2 Display Modes

The clock supports multiple display modes, which can typically be cycled through by pressing a specific button (often the UP or DOWN button when not in setting mode). The available modes include:

• Time-Temperature
• Time-Date-Week
• Time-Temperature-Date-Week

4.3 Setting Time and Date

To set the time and date:

1. Press the SET button to enter the setting mode. The first parameter (e.g., hour) will start blinking.
2. Use the UP or DOWN buttons to adjust the value.
3. Press SET again to move to the next parameter (e.g., minute, year, month, day).
4. Repeat until all parameters are set. Press SET one last time to exit the setting mode.

4.4 Alarm Settings

The clock supports up to three alarms. To set an alarm:

1. Enter the alarm setting mode (usually by pressing SET multiple times until 'AL1' or similar appears).
2. Use UP/DOWN to set the alarm hour and minute.
3. Enable/disable the alarm and set the alarm to work on specific days (e.g., Monday to Friday).
4. Repeat for AL2 and AL3 if desired.

4.5 Temperature Display

The temperature can be displayed in Celsius (°C) or Fahrenheit (°F). This setting is typically found within the general settings menu. Use the UP/DOWN buttons to select the desired unit and SET to confirm.

4.6 Brightness Adjustment

The clock features adjustable brightness and an automatic brightness mode via a light sensor. To adjust:

• Access the brightness setting in the menu.
• Use UP/DOWN to select a manual brightness level or enable the automatic brightness feature.

4.7 Other Features

• Time Correction: A function to improve clock accuracy. Refer to the online tutorial for detailed calibration steps.
• Hourly Chime: Can be set to prompt during specific hours (default 7:00-21:00).
• Built-in Music: Includes three melodies (To Alice, Ode to Joy, Spanish Matador) for alarms.
