Trying to write an event listener with Teensyduino 2.0

Projects General Guidance

I'm trying to listen to triggers from hall effect sensors on my teensyduino 2.0 board, and I'm having a lot of trouble coding this correctly. As it stands right now, my key press event isn't actually releasing. My thought is that there must be a way to actually trigger the board rather than run an infinite loop?

Here is the code I've written

int laneOnePin = 5;
int laneTwoPin = 6;
int laneThreePin = 7;
int laneFourPin = 8;

int redPin =  12;
int greenPin =  15;
int bluePin =  14;

int laneOneTrigger;
int laneTwoTrigger;
int laneThreeTrigger;
int laneFourTrigger;

void setup()   {                
  Serial.begin(38400);
  pinMode(laneOneTrigger, INPUT);
  pinMode(laneTwoTrigger, INPUT);
  pinMode(laneThreeTrigger, INPUT);
  pinMode(laneFourTrigger, INPUT);
  pinMode(redPin, OUTPUT);
  pinMode(greenPin, OUTPUT);
  pinMode(bluePin, OUTPUT);
  
   // initialize control over the keyboard:
  Keyboard.begin();
}

void loop()                     
{
  laneOneTrigger = digitalRead(laneOnePin);
  laneTwoTrigger = digitalRead(laneTwoPin);
  laneThreeTrigger = digitalRead(laneThreePin);
  laneFourTrigger = digitalRead(laneFourPin);
  
  Serial.print("magnet is: ");
  
  if (laneOneTrigger == 0) {  
    Serial.println("near lane one");
    // Turn USB red
    analogWrite(redPin, 255);
    analogWrite(greenPin, 0);
    analogWrite(bluePin, 0);
    Keyboard.press(KEY_LEFT_CTRL);
    Keyboard.press(KEY_LEFT_ALT);
    Keyboard.press(KEY_F1);
    delay(200);
    Keyboard.releaseAll();
  } else if (laneTwoTrigger == 0) {  
    Serial.println("near lane two");
    // Turn USB yellow
    analogWrite(redPin, 255);
    analogWrite(greenPin, 255);
    analogWrite(bluePin, 0);
    Keyboard.press(KEY_LEFT_CTRL);
    Keyboard.press(KEY_LEFT_ALT);
    Keyboard.press(KEY_F2);
    delay(200);
    Keyboard.releaseAll();
  } else if (laneThreeTrigger == 0) {  
    Serial.println("near lane three");
    // Turn USB green
    analogWrite(redPin, 0);
    analogWrite(greenPin, 255);
    analogWrite(bluePin, 0);
    Keyboard.press(KEY_LEFT_CTRL);
    Keyboard.press(KEY_LEFT_ALT);
    Keyboard.press(KEY_F3);
    delay(200);
    Keyboard.releaseAll();
  } else if (laneFourTrigger == 0) {  
    Serial.println("near lane four");
    // Turn USB blue
    analogWrite(redPin, 0);
    analogWrite(greenPin, 0);
    analogWrite(bluePin, 255);
    Keyboard.press(KEY_LEFT_CTRL);
    Keyboard.press(KEY_LEFT_ALT);
    Keyboard.press(KEY_F4);
    delay(200);
    Keyboard.releaseAll();
  } else {
    Serial.println("not near any lane");
    delay(200);
    Keyboard.releaseAll();
    analogWrite(redPin, 0);
    analogWrite(greenPin, 0);
    analogWrite(bluePin, 0);  
  }
    
  delay(10);
}

Any suggestions would be fantastic!! Thank you.

There is a Teensy forum here: PJRC (Teensy) Forum

Thank you, I posted on that forum as well. I am sorry, I thought that the Arduino forum was universal :frowning:
