3X Electronic Digital Clock Kit C51 Microcontroller Learning Board DS1302 Rotating LED Module DIY Production Parts

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.
