LED earring
This circuit I found on the internet because I found it interesting here I will share with you.
Christmas is already over and the New Year's fireworks extinguished. Almost. This makes the new year and still sparkles glitters, Elektor has poached in the jewelry industry.
Properties:
- Microcontroller controlled earring with customizable light patterns
- Lightweight board with eight symmetrically arranged LEDs
- Low power consumption (12 mW thanks multiplexed LEDs)
- Good base for your own extensions
