So I am creating a password system using Neopixels and an IR remote. Lighting up each pixels once a button is pressed. I created 4 array variables with list of numbers inside to be used later. I also initialised z variable to be use later on the last part to check if the passwords are correct. Correct = all pixel blink green 3 times. Wrong all light up as red for 2 seconds. So my question is, for every if statements on the first part, do the digits actually get stores on the y[z] array? And, am I right to use if( z =8) to check if the number of digits inside y[z] is already 8 to start checking the password? Because, it does not seem to work, it does not enter in the if statements when checking if the password is correct or not. Also, the serial monitor is only showing 0s instead of the number of the button I am pressing :// is my application of array wrong? Thank you!

so my serial monitor only prints out as 3, instead of 14234343
