+This video presents the base functionalities of the smart clock: * The **OLED screen** displays real-time data: current time, ambient light level (lux), and the active RGB color index. * The **RGB LED** changes color with each short press of **BTN MODE**, cycling through 7 predefined colors. * Holding **BTN MODE** triggers a visual feedback mode where the RGB LED blinks white at 4 Hz. * The **Dim mode** (based on LDR readings) reduces LED brightness in low light conditions. * The **hour** and **minute buttons** allow manual time adjustments.
+https://streamable.com/ryv6rw
+This clip shows the additional functionality activated after 19:00: * The **red LED** (D5) no longer blinks but gradually brightens depending on the current **hour**. * The **green LED** (D6) lights up with intensity proportional to the current **minute**. This simulates a simple hour-and-minute hand system using LED brightness. After 00:00, both LEDs return to their standard behavior (blinking and minute-flash). Additionally, the **RGB LED** adapts to ambient light using the **LDR sensor**. When you shine light onto the photoresistor, the RGB LED's brightness increases accordingly.
+In darker environments, the RGB LED automatically dims (enters **dim mode**) for smoother visual integration during nighttime.
