LED Shifter Board
This project powers two banks of LEDs, to be installed in a jar or vase. A hand-wired circuit outputting to 16 rows of LEDs and controlled by 3 input lines. An Arduino development board is used to prototype and test code, with plans to use a standalone chip (attiny13 or attiny261) in the final installation.

Analog Input Board
This project drives a six-digit display and reads values from analog inputs. This board uses a shift register to drive a set of seven-segment displays, all being controlled by an ATmega328P processor. Planned serial control/data transfer via terminal or as a peripheral to another system.

- MSGEQ7 Graphic Equalizer chip with Arduino
The MSGEQ7 chip outputs in 7 EQ bands, and I currently map 6 of those to two RGB LEDs. (Channels 1,2,3 to red, green, and blue of one LED, etc.) I plan on using a an extra set of white LEDs to show the last channel.
