Analog pins all reading same value

Question

I'm trying to read 5 analog inputs, but all the pins are reading the same as pin A0, plus or minus a couple points. I tried using pulldown resistors on all 5 pins and it made no difference. The board is a Leonardo. Thanks for any ideas/help!

void setup() {
 Serial.begin(115200);
 analogReference(EXTERNAL);
}
void loop() {
 int A0, A1,A2,A3,A4;
 delay(200);
 A0= analogRead(A0);
 A1= analogRead(A1);
 A2= analogRead(A2);
 A3= analogRead(A3);
 A4= analogRead(A4);
 Serial.print(A0);
 Serial.print(" ");
 Serial.print(A1);
 Serial.print(" ");
 Serial.print(A2);
 Serial.print(" ");
 Serial.print(A3);
 Serial.print(" ");
 Serial.print(A4);
 Serial.print("\n");
}

Answer 1

int A0, A1,A2,A3,A4;
delay(200);
A0= analogRead(A0);
A1= analogRead(A1);
A2= analogRead(A2);
A3= analogRead(A3);
A4= analogRead(A4);

Your local variables (A0 through A4) are shadowing the global variables for the pins (A0 through A4). Give your local variables different names.
