Color Mixer

I soldered leads to the piezo buzzer included in the Arduino starter kit because the pins on the buzzer itself are too short and the component takes too much room on the breadboard if plugged in by the pins.

For my Stupid Pet Trick, I made a color mixing LED with analog input and output by modifying the fourth project from the Arduino Projects book. I substituted the phototransistor inputs with potentiometers to allow users to manually adjust the amount of red, green, and blue light the LED emits.
