Four LEDs, two DC Motors and a voltmeter (along with appropriate resistors as needed) are connected to an Arduino. The following code will be executed on the Arduino.

Arduino Uno Code:

void setup()

{

pinMode(12, OUTPUT);

pinMode(4, OUTPUT);

pinMode(2, OUTPUT);

pinMode(13, OUTPUT);

digitalWrite(12, HIGH);

digitalWrite(4, HIGH);

digitalWrite(2, HIGH);

digitalWrite(13, HIGH);

}

void loop()

{

delay(2000);

digitalWrite(4, LOW);

delay(2000);

digitalWrite(2, LOW);

delay(2000);

digitalWrite(12, LOW);

delay(2000);

digitalWrite(13, LOW);

delay(2000);

digitalWrite(4, HIGH);

delay(2000);

digitalWrite(2, HIGH);

digitalWrite(13, HIGH);

digitalWrite(12, HIGH);

}

When the sketch is run, the system will go through a 12-second cycle as shown in Table 1 and continue repeating the pattern. In the ON state, the LEDs can have any brightness as long theyre visibly ON. When turned on, Motor-1 rotates only clockwise (with a positive rpm) and Motor-2 rotates only counter-clockwise (with a negative rpm). The voltmeter reading should be close to 2 V if not exactly 2 V (Hint: use a voltage divider).

Once you determine what the connections are, run the sketch and confirm that it properly goes through the six states periodically as listed in Table 1.

In your report, include a clear screenshot of the circuit connections when the system is in State-2. Specify the resistor values you used.

Hardware or Software platform for solution is fine!
