An RGB LED Mixer built only with the parts from the Fritzing starter kit.
This is a simple mixer to experiment with the RGB-LED from the starter set. Since the starter set only has one potentiometer, you may choose the colour to fade with the buttons.
The single colour LEDs indicate the selected colour ( you need to replace the blue LEDs with yellow ones as the starter set does not provide blue LEDs ). You can select the active colour with the left button. The right button activates fading: The current LED will start to blink and you can fade the corresponding RGB-LED colour with the knob.
I needed to create a custom part for the RGB-LED since there was none in the standard parts list. Also I did not pay too much attention to the schematic and the PCB layout as I do not think that anybody will etch a PCB for this :-)
