Arduino Uno Code:

int redOn = HIGH; int greenOn = HIGH; void setup() { pinMode(2, OUTPUT); pinMode(4, OUTPUT); digitalWrite(2, redOn); digitalWrite(4, greenOn); Serial.begin(9600); } void loop() { delay(10); // Delay a little bit to improve simulation performance digitalWrite(2, redOn); digitalWrite(4, greenOn);

if(Serial.available()){ char c = Serial.read(); if (c == 'r'){ if (redOn == HIGH){ redOn = LOW; Serial.println("Red LED Off"); } else{ redOn = HIGH; Serial.println("Red LED On"); } } if (c == 'g'){ if (greenOn == HIGH){ greenOn = LOW; Serial.println("Green LED Off"); } else{ greenOn = HIGH;

Serial.println("Green LED On"); } } } }

Question:

Based on the code provided, add the following three functions to the circuit:

1. If a is typed into the serial monitor, both LEDs turn on and the message All LEDs On is displayed.
2. If o is typed into the serial monitor, both LEDs turn off and the message All LEDs Off is displayed.
3. If a character other than r, g, a or o is typed into the serial monitor, the message Unknown Command is displayed.

Please provide Arduino code! Thanks!
