Picture of Twinkling LED Ribbon Necklace.
In this instructable we will show you how to make a ribbon necklace embedded with blinking LEDs. The LEDs are powered by a coin cell through conductive thread and it is controlled by a LilyTiny microcontroller board. Since the LilyTiny comes with pre-programmed LED blink patterns you need not do any coding at all! Plus the electronics involved is quite simple to implement. This is a simple and effective introduction into wearable electronics for beginners!
