Description
My project for the Celebrate Childhood OSHWLAB Event
It's a PCB in the shape of a star using the colorful silkscreen technology, made in EasyEDA Pro.
It uses an ATtiny microcontroller and a shift register to drive LEDs all around the board and optionally a few LEDs can also be mounted on the back side for a glowing effect.
Note that I'm not providing code for the microcontroller since it's a DIY project, everyone can write their own code to light the LEDs in the desidered pattern.
The shift register is connected as follows:
SER - PB2
OE (Output Enable) - PB3
RCLK - PB1
SRCLK - PB0
The logic of the LEDs is inverted, HIGH means OFF, LOW means ON
