Dial controlled RGB moodlight
With this lamp you can set your ambient light color according to your mood. It is based on PIC12F675 microcontroller and it's controlled with a potentiometer and a pushbutton.
Microcontroller reads the potentiometer value with it's A/D converter and sets color change speed (fading efect) or final wanted color, depending on current lamp's mode. Modes are changed with a pushbutton. It sure is a pretty cool mushroom-shaped lamp!
