03-03 IfElseSwitch
From Manuals
Flashes one of two LEDs, depending on the state of a 2-way switch. The LEDs are connected to D0 and D1 of J9. The switch is connected to D2 of J9.
Please see schematic below for further details.

wait(0.2);
redled = 0;
wait(0.2);
} //end of if
else { //here if switchinput is 0
redled = 0; //red led is off
greenled = 1; // flash green led
wait(0.2);
greenled = 0;
wait(0.2);
} //end of else
} //end of while(1)
