  • Create a program that will blink two LEDs; one red, one green, alternately. That is, when the red LED comes on, the green should turn off and when the green comes on, the red should turn off. The red should be on for two seconds and the green should be on for one second. At no time should both LEDs be on simultaneously or off simultaneously (at least not within ordinary human perception). This blinking pattern should repeat over and over: red on for two seconds, green on for one second, red on for two, green on for one, and so on.

    Include your code and a proper schematic diagram with component values. It is suggested that Multisim or another schematic capture program be used to generate the schematic.
