## Assembly Instructions
1. **Power Supply Setup**:
- Connect the 14250 battery to the TP4056 module for safe charging and protection.
- Wire the output of the TP4056 to the **3.3V pin** on the D1 Mini to power the device.
- Connect the **5V output pin** from the D1 Mini to the **input port** on the TP4056 module to enable charging functionality.
2. **OLED Display**: Solder connections for SDA (D2, GPIO4) and SCL (D1, GPIO5) to the respective pins on the D1 Mini.
3. **Buttons**: Attach each button to the specified GPIO pins with pull-down resistors to ensure reliable input.
4. **Buzzer**: Connect the piezo buzzer to GPIO0. Ensure proper polarity. Negative to the GPI00, Positive to 3.3v
5. **Enclosure**: Assemble all components in a secure housing. May require some hot glue to keep components in

## Notes
- This is still a work in progress
- Everything is pretty tightly packed in there. But it's not as hard to make as it looks.

- Ensure all connections are secure to avoid malfunction. Hot glue is your friend.

- Test the circuit thoroughly before placing and glueing it in the enclosure.
- Battery is the trickiest part to fit in, it's best to glue the charing module directly to it and put it in the case last:
