## Description

DIY kit for learning soldering and basic electronics, with easy-to-assemble THT components. Assemble a small photosensitive robot that follows a flashlight through two vibrating motors, and the 5mm blue LED automatically pulses like a firefly. Includes all the necessary parts on a PVC base, 3V power supply with CR2032 battery not included.
DIY Kit Licurici (LED Breathing Light), created especially for those who want to experiment with soldering and building simple circuits. This kit offers a captivating educational experience, being also ideal for beginners, having only THT (Through Hole Technology) components.
The circuit design is easy to assemble, and all the necessary components are included to build your own mobile robot with a blue tail light that turns on automatically, mimicking the natural behavior of fireflies.
The kit is not just a simple component soldering project, but a perfect educational tool to learn the basic principles of electronics and soldering. The resulting robot has two vibrating motors and two photoresistors. When pointing a flashlight at it, through the alternating vibration of the legs, the robot will orient itself towards the light source.
It is necessary to be powered by a CR2032 battery ( not included ).
Specifications:
Base material: PVC sheet
Supply voltage: DC 3V
Battery type: CR2032 (battery NOT included)
Detection device: Photosensor (photoresistor)
Tail LED: 5 mm blue LED
Instructions for use:
Assemble the components on the PVC base according to the diagram and the indications directly on the PCB, paying particular attention to the polarity and the mounting direction of the IC (see the crescent).
Use a soldering gun to fix the electrical components.
Insert the CR2032 battery for power and check if the circuit works correctly.
The photosensitive sensor will detect the light, and the tail LED will start to pulse automatically, imitating the effect of a firefly's breathing.
