Merging this Sketches

Im trying to combine these two sketches so that the buttons are replaced by these LINK break beam sensors and am having no luck with anything I try.

Can anyone help please?

Show us what you tried and what the results were. "Having no luck" is not a very good problem description.

Hi, Some suggestions here:

Here is what I had so far, just focusing on Switch one, as Im a little unsure on "sensorState" in the sketch and how it would work with 2 if your defining for one in the original Break beam sketch.

Also, when I add Library "LedControl.h" it is dark green in the sketch, all other libraries I add are orange. I was told to ignore it, but could there be something wrong with the library I downloaded as it pertains to the sketch? maybe not running the max7219 correctly? Ledcontrol.h

#include "LedControl.h" // Library used for communcation with 7 segment

LedControl lc=LedControl(12,11,10,1); // (DIN, CLK, LOAD, number of Max7219 chips)

int displayone=0;
int displaytwo=0;

// Variables to split whole number into single digits
int rightdigit;
int leftdigit;
int sensorState = 0, lastState=0; // variable for reading the pushbutton status

// Switches pin connection to Arduino UNO
#define switchone 2
#define switchtwo 3

void setup() {
pinMode(switchone, INPUT);
pinMode(switchtwo, INPUT);
digitalWrite(switchone, HIGH);
digitalWrite(switchtwo, HIGH);

lc.shutdown(0,false); // Wake up MAX7219

lc.setIntensity(0,7); // Set brightness to medium

lc.clearDisplay(0); // Clear all displays connected to MAX7219 chip #

// Put zeros on both displays at startup

lc.setDigit(0,0,0,false); // (Max7219 chip #, Digit, value, DP on or off)
lc.setDigit(0,1,0,false);

lc.setDigit(0,2,0,false);
lc.setDigit(0,3,0,false);

Serial.begin(9600);

}

void loop() {
sensorState = digitalRead(switchone);

// If switch 1 is clicked
if (sensorState == LOW) {

displayone++; // Increase score by 1

// convert whole number to single digits
rightdigit=displayone%10;
leftdigit=displayone%100/10;

lc.setDigit(0,0,leftdigit,false);
lc.setDigit(0,1,rightdigit,false);

while (sensorState == LOW) {
}

}

if (!digitalRead(switchtwo)) {

displaytwo++;

rightdigit=displaytwo%10;
leftdigit=displaytwo%100/10;

lc.setDigit(0,2,leftdigit,false);
lc.setDigit(0,3,rightdigit,false);
