LED Photosensitive Sensor Mobile Robot Kit DIY Electronic Soldering Practice Kit

About this deal

This is a firefly-themed photosensitive mobile robot soldering kit. It simulates the automatic flashing of fireflies and, using its photosensitive sensor, moves automatically towards light. Two photosensitive sensors on the left and right act as antennae; when light reaches either sensor, the corresponding transistor activates a small vibrating motor, causing the robot to move in the direction of the light. The flashing frequency of the blue LED tail light can be adjusted via a potentiometer. Power comes from a CR2032 button battery, which is not included. The kit is aimed at electronics beginners, students, and hobbyists looking to build their soldering skills. It requires a basic soldering foundation, comes with step-by-step instructions, and is well suited for beginners to practise soldering. Component connections are clearly mapped and labelled on the board, making assembly straightforward. Note that this is an unassembled kit requiring manual soldering; a soldering iron and batteries are not supplied.
