This electronic clock is designed based on the digital tube display principle and plug-in , and has a high production success rate. Contains six time animations to effectively and vividly display time and functions. The LED flash includes four offline animation display modes, and the lighting effects are highly decorative, bringing great aesthetics to homes and table settings. The electronic clock uses alternate display of time and temperature, accurate travel time and has a power-off memory travel time function. It has an alarm clock function that can be turned on and off. With light control function, it can automatically adjust the brightness according to the environment. It has an alarm clock function that can be turned on and off. With light control function, it can automatically adjust the brightness according to the environment. Circuit principle: A microcontroller is used as the main control, and the DS1302 travel time chip is used to provide an accurate travel time clock source, and the specific time value is displayed in combination with a digital tube and LED lights. And combined with the temperature light intensity detection elements, it realizes its accompanying brightness adjustment and temperature detection functions. The keys are controlled by the microcontroller and the necessary key input adjustment functions are performed. The clock sound is processed by the microcontroller and then buzzed. device is issued. Material: plastic colour: As Shown Package Contents: 3 x electronic clock kit Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
