// In this program is made turning on white, yellow and red led according to potentiometer output.
// In case of switching the switch to ON position, red LED turns ON and blue led blinks 5 times. !HARDWARE INTERRUPT!
// After that, red LED stays ON, while white and yellow can be switched ON or OFF according to potentiometer output.
// When switch goes back to OFF position, blue LED blinks for 2 times and the program goes back to standard mode.
// Internal green LED blinks every 0.2 seconds to indicate that the program is running. !TICKER!
