Photosensitive Firefly Kit Mobile Robot Electronic DIY Welding Parts Breathing Light Fun Electronic Manufacturing Circuit Board

Product Name: Photosensitive Firefly Robot KitWorking voltage: DC3V (CR2032 button battery)Board size: 40 * 43mmSensor: PhotoresistorPhotosensitive movement: The antennae of the firefly's head can sense the presence of light. When light shines on the left and right antennae R1 or R4, the transistor Q1 or Q2 conducts, and the corresponding motor installed on the legs begins to vibrate. The firefly will move in the direction of sensing light.Tail breathing lamp: The breathing lamp circuit is

Product Name: Photosensitive Firefly Robot Kit

Working voltage: DC3V (CR2032 button battery)

Board size: 40 * 43mm

Sensor: Photoresistor


Photosensitive movement: The antennae of the firefly's head can sense the presence of light. When light shines on the left and right antennae R1 or R4, the transistor Q1 or Q2 conducts, and the corresponding motor installed on the legs begins to vibrate. The firefly will move in the direction of sensing light.



Tail breathing lamp: The breathing lamp circuit is composed of LM358 operational amplifier IC, simulating the luminous effect of fireflies turning on and off in dark environments.
