// This program shows a PWM LED dimming while outputing the settings. When //
// started up it will show the onboard LED burning and the tricolor LED will //
// fade the red LED and show the Green and Blue LED in a fainted way. You can //
// alter the changing LED in Green or Blue by opening the Serial monitor and //
// entering a gG or bB or rR. Also the IR remote TV control unit can be used //
// to switch the light color. 1=red 2=Green 3=Blue. Next stwep is to integrate//
// the engines. 1=Red=Rest, 2=Green=GO, 3=Blue=Backwards. You can also enter //
// the Serial monitor commands r, g or b. The speed encoders have also been //
// implemented. You could use the EEPROM to remember the last settings. //
