 To implement the LCD functionality, we used the example codes provided in the [ESP-IDF examples](https://github.com/espressif/esp-idf/tree/release/v5.3/examples/peripherals/lcd), which cover various LCD interfaces. We also used the [esp_lv_spng](https://components.espressif.com/components/espressif/esp_lv_spng/versions/0.1.0) component to efficiently display PNG images on the LCD. The [LCD Screen User Guide](https://docs.espressif.com/projects/esp-iot-solution/en/latest/display/lcd/lcd_guide.html#lcd-introduction) offers additional insights into LCD integration.
 
 - **Motor Driver and Buzzer:**
-The motor driver and buzzer are controlled via the PWM interface. Espressif provides a [LEDC example](esp-idf/examples/peripherals/ledc) that demonstrates how to implement PWM for such applications. The [LEDC Programming Guide](https://docs.espressif.com/projects/esp-idf/en/v5.3/esp32c2/api-reference/peripherals/ledc.html#led-control-ledc) offers further details. For controlling the buzzer, we utilized the [hayschan/buzzer](https://components.espressif.com/components/hayschan/buzzer/versions/1.0.0) component to simplify the software development and achieve better sound effects.

 - **Battery Power Monitoring:**
 We implemented battery voltage monitoring using the ADC interface, referring to the [ADC oneshot read example](https://github.com/espressif/esp-idf/tree/release/v5.3/examples/peripherals/adc/oneshot_read). The [ADC Oneshot Mode Driver Guide](https://docs.espressif.com/projects/esp-idf/en/v5.3/esp32c2/api-reference/peripherals/adc_oneshot.html?highlight=adc#analog-to-digital-converter-adc-oneshot-mode-driver) provides further instructions on how to read ADC data in oneshot mode.
