DIY Soldering Photosensitive Mobile Robot Kit

This DIY soldering kit mimics the shape of a firefly. When the switch is turned on, an LED light in the tail blinks like a firefly. When light enters the antennae, the support points at the bottom begin to vibrate, causing the firefly to move.
This DIY electronic kit is very suitable for beginners, the parts are simple, and the installation positions of the parts are clearly printed on the PCB board, so you can easily find the corresponding positions for soldering (detailed installation steps will be shown in the description below).
