Product Description
Working voltage
dc4.5v~5v
Kit principle
Photosensitive resistor RG and V1 and RP1 form a light control circuit, so that the circuit only works at night. During the day, the photoresistor RG is illuminated, the resistance value becomes smaller, V1 is turned on, and the seventh pin of IC1 is pulled low at the low level, IC1 The oscillator circuit is stopped and the circuit does not flash. At night, the resistance of RG becomes larger, V1 is cut off, the 7th pin of IC1 becomes high level, the oscillation circuit starts to work, and LED1 and LED1 emit flash.
