Hello. I am doing my first project on the Arduino. I have some decent experience in programming c++/Java, however i never did it for arduino. And one important note i never used bitwise operations in C. I created this short program as a test but its not working as it i intended it to. The idea is that i have 8 shift registers (74HC595) and i wanted to create some code that will let me test if everything is set up well. The issue is that just the first register out of the 8 displays data using my function. I assume that i made something wrong in the bitwise operations but even after looking in the internet i cannot see the problem, so here i am.
int clk = 2;
int latch= 3;
int data1 = 4;
int data2 = 5;
int data3 = 6;
int data4 = 7;
int data5 = 8;
int data6 = 9;
int data7 = 10;
int data8 = 11;
byte val1 = B00000001;
byte val2 = B00000010;
byte val3 = B00000100;
byte val4 = B00001000;
byte val5 = B00010000;
byte val6 = B00100000;
byte val7 = B01000000;
byte val8 = B10000000;
void setup(){
for(int i = 2; i < 12; i++){
pinMode(i, OUTPUT);
}
digitalWrite(clk, LOW);
digitalWrite(latch, LOW);
reset();
}
void loop() {
//digitalWrite(5, HIGH);
delay(500);
shift(val1);
delay(500);
//reset();
shift(val2);
delay(500);
shift(val3);
delay(500);
shift(val4);
delay(500);
shift(val5);
delay(500);
shift(val6);
delay(500);
shift(val7);
delay(500);
shift(val8);
delay(500);
}
//------------------------------------------------
void shift(byte values){
byte val = values;
for(int i = 4; i < 12; i++){
digitalWrite(4, val & 1);
val = val >> 1;
}
digitalWrite(clk, HIGH);
digitalWrite(clk, LOW);
show();
}
void reset(){
for(int i = 4; i < 12; i++){
digitalWrite(i, LOW);
}
digitalWrite(clk, HIGH);
digitalWrite(clk, LOW);
}
void show(){
digitalWrite(latch, HIGH);
digitalWrite(latch, LOW);
}
From what i checked so far the registers are hooked up correctly and they work (the commented out lines were for that purpose). When i run this program the first line which is meant to display B00000001 which means only the first register should light up works fine but the other 7 bytes do not work. I assume that my right shift in the shift() method does not properly right shift the values. I cant see whats the issue in my code 
NOTE: Im using only the first output of the registers and each has a LED with resistor attached, so thats how i check the output data.
