Quick suggestion on approaching this problem

My current code is this

const int LaserC=2;
const int CellC=A0;

int thres=830;
int chqC=0;
int store=0;

void setup() 
{
  Serial.begin(9600);

  pinMode(LaserC,OUTPUT);


}

void loop() 
{

  digitalWrite(LaserC,HIGH); 


  chqC= analogRead(CellC);

  if (chqC<thres)
  {
    store=HIGH;
  }    

  else if (chqC>=thres) 
  {
    store=LOW;
  }



  if ((store==HIGH) && (chqC>=thres))
  {
    Serial.print("a");
  }
}

dc42:
Try this:

const int threshold = 830;

bool cellC_active = false;

void setup()
{
 Serial.begin(9600);  
 pinMode(LaserC,OUTPUT);
 digitalWrite(laserC, OUTPUT);
}

void loop()
{
 bool cellC_wasActive = cellC_active;    // remember whether the cell was already active
 cellC_active = (analogRead(CellC) >= threshold);   // update the active/inactive state
 if (cellC_active && !cellC_wasActive)   // if the state has changed from inactive to active...
 {
     Serial.print("a");   //... then log to serial monitor
 }
}




Then read about arrays to find out how to generalise it to multiple strings.

Your code works MUCH better than mine and works the way I want when in the serial monitor however it is still pressing the key too fast and doesn't press the note. Is there any way I could possibly tweek this to work a little bit better?

Edit:
Okay so I have been testing out the code dc42 posted and I am noticing that when I am in the serial monitor everything is working as needed, however when I run aac keys I notice that sometimes when I go to cover the laser, that the actual laser cuts out and will blink at random on it's own. I noticed the laser do this with other codes but I figured it might have had something to do with my code being 'wonky'.
