This printed circuit in the shape of butterfly wings is decorated with LEDs that give the illusion that the butterfly is flapping its wings.
Just touch its two antennas together and the red LEDs will blink. The circuit uses a clock and an offset register to create the sequence in which the LED bulbs light up.
- 8 red LEDs, circuit board
- Requires basic oldering skills, soldering tools and 3V CR2032 battery (not included)
