Description:
1.Photosensitive movement:
The antennae on the head of the firef1y can perceive the presence of light. When the light hits the left and right antennae R1 or R4, the transistor Q1 or Q2 is turned on.
The motor corresponding to the installed leg will start to vibrate, and the firef1y will move in the direction of the sensing fiber.
2. Tail breathing light:
The breathing light circuit is composed of LM358 operational amplifier IC, which simulates the glow effect of fireflies slowly turning on and off, embellishing the world like real fireflies in the dark environment.
3. Assembly instructions:
First, use pliers or tweezers to carefully break the pins of the button battery holder outward into a right angle, and then solder the leads.
The welded PCB, transparent base, vibration motor, and battery holder are all glued together, and finally the leads are welded.
The components are welded in order from short to high, pay attention to distinguish the positive and negative poles, there should be no false welding, and the power supply can not be reversed.
4. Through the welding and assembly of this kit, you can understand some basic electronic components and improve your hands-on ability. It is a good choice for beginners.
