Arduino source code: resistive joystick exercise

JoyStickTest.ino

// Joystick exercise

#define JOYY A1
#define BUTTON 7

int JoyX,JoyY;
boolean Button;

//-- Helper routine for printf()

int s_putc(char c, FILE *t) {
  Serial.write(c);
}


void setup() {

  Serial.begin (9600);

  Serial.println ("Joystick exercise");
  Serial.println ("Ed Nisley - KE4ZNU - May 2017");

  pinMode(BUTTON,INPUT_PULLUP);
}

void loop() {

  JoyX = analogRead(JOYX);
