Photosensitive firefly robot DIY electronic production kit. The antennae on the firefly’s head can sense the presence of light. When the light hits the left and right antennae R1 or R4, the transistor Q1 or Q2 is turned on, and the corresponding motor installed on the leg will start to vibrate. It will move in the direction of the perceived light.
The tail breathing light uses an LM358 op-amp IC to form a breathing light circuit, simulating the glowing effect of fireflies slowly turning on and off, just like real fireflies in a dark environment.
