Write code to control the colour sequence of 3 leds, Red, Yellow, Green on 3 pins of your choice. Use a two dimension array 4 rows by 3 columns to sequence the LEDs. Each column holds the on/ off state of the LED, and each row is the next step in the sequence 1 second apart. Also use Serial.Event to change the state of the LEDs from the Serialport The code should be a complete arduino program and should compile and run.
