Story

At first I was intimidated because this project jumped into applying code. The resistors, LEDs, and switch, are the most complex combination of components so far. The goal was to have the leds alternate when the switch was pressed.

The most challenging aspect of the project was balancing code errors with hardware errors. I struggled to ensure that each LED was functioning correctly and lighting up in the correct sequence. It took a lot of trial and error to get the code just right, but I was determined to succeed.

The project took two hours to complete. The green LED is supposed remain lit when the switch isn't pressed, indicating that the functionality is on standby. When the switch was pressed, the two red LEDs are supposed to alternate back and forth in an interval, indicating that the process is running.

I personally rate the difficulty level of this project as moderate. It definitely required some technical knowledge, but wasn't too complex. However, the challenge came from ensuring that all of the components were working together correctly.

In the future, I can see this project being modified into a personal project by adding more LEDs or different colored LEDs to indicate different stages of a more complex process. Additionally, the switch could be replaced with a sensor that automatically detects when a process is ready or running.

Arduino Sketches

int SwitchState = 0;

void setup() {
  Serial.begin(9600);
  pinMode(2, INPUT);
  pinMode(3, OUTPUT);
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
}

void loop() {
  SwitchState = digitalRead(2);

  // Run switch code.
  OnSwitch();
}
void OnSwitch() {
  // Handle led control through switch state.
  switch (SwitchState) {
    case 0:
      Serial.println(" ");
      Serial.println(" ");
      Serial.println("Switch is NOT pressed!");

      digitalWrite(3, HIGH);
      digitalWrite(4, LOW);
      digitalWrite(5, LOW);
      break;
    case 1:
      Serial.println(" ");
      Serial.println(" ");
      Serial.println("Switch IS pressed!");

      digitalWrite(3, LOW);
      digitalWrite(4, LOW);
      digitalWrite(5, HIGH);
      delay(250);
      digitalWrite(4, HIGH);
      digitalWrite(5, LOW);
      delay(250);
      break;
  }
}
