Modulated Dimmer Project
Description
This project creates firmware that color mixes three primary high-brightness LEDs to a single color,
modulates the brightness and introduces optical feedback into the system using a color sensor.
The user can then choose the Tuner to select other desired colors mapped along the 1931 CIE XYZ
Color Space.
The tuner enables turning ON/OFF the LEDs and adjusting the resultant flux output, over an I2C
interface. By default, the firmware will automatically generate a single color inside the defined color
gamut and modulate the brightness.
The project utilizes four different Interface (Communication) Valuators. Each set a specific register
which can be modified using the available tuner. The LEDEnable controls the 3LED ColorLock
Driver, the LEDTrigger controls the optical feedback loop and the xValuator and yValuator registers
create a color based on x,y coodinates in the 1931 CIE XYZ Color Space. Also utilized are a priority
encoder named LEDBrightness valuator which controls a modulated flux value. Next, the program
contains a timing element which feeds a state machine. This timing element controls the length of
time it takes to dim the LEDs from full intensity to OFF. Finally, the 3-LED ColorLock Driver controls
the LM3404 Switching Regulators to power the LEDs.

WARNING: HIGH BRIGHTNESS LEDs CAN CAUSE PERMANENT
EYE DAMAGE!
Do not look at the LEDs if they are not covered by the protective
enclosure. The LEDs illuminate at a very high intensity and can
cause permanent eye damage if they are viewed without the
protective enclosure.
