TLC5940 RGB Flower Necklace
Rainbow flower necklace using the TLC5940.
The
TLC5940 chip
gives us
Pulse Width Modulation (PWM)
control over 16 outputs. We plug in 5 RGB LEDs to make this RGB Flower necklace. Using the 14 channels of PWM we can display a full-spectrum of rich rainbow colors on your neck!
Get your very own RGB flower necklace
, at the LucidTronix store. The chain comes from
ohio beads
, they have lots of nice jewelry components. Also check out our
tutorial for to driving the TLC5940 chip
