Arduino Joystick with Led Matrix Display

Project 30:  Joystick controls a Led Matrix Display

This project challenges the maker to incorporate a motion detector sensor,
a speaker, and a joystick that controls a led matrix display,






Hardware:
1 PIR Motion Sensor
1 Led (indicator)
1 joystick
1 speaker
1 Led Matrix Display
connecting wires
breadboard
Arduino R3 UNO board


Connection Pins:

 DataPin, din = 12;
 LatchPin, cs  = 10;
 ClockPin, clk = 11;
 Speaker= 4;               
 Led = 13;                
 Motion Sensor, S = 5;
 Joystick x,y = A0, A1;
 Vcc, +   = 5V;
 Gnd, -   = ground;

  

Sample Sketch for PIR and Matrix Display :

/*
  iHacklab Led Matrix Display controlled by a joystick
  This sketch does the following procedures:
1. Buzzer when motion is detected
2. Display graphix when there is no motion detected.
3. Joystick controls an led in a matrix display
4. Circuit connections embedded

Sample sketch for Joystick/Matrix:

int A0 = 0;  //x
int A1 = 1;  //y
int Zkey = 3;    //z

LedControl lc=LedControl(12,11,10,1);

  pinMode(z,input);
  lc.shutdown(0,false);
  lc.setIntensity(0,5);
  lc.clearDisplay(0);

}

  X= analogRead(A0);
  Y= analogRead(A1);
  Z =digitalRead(Zkey)
  char x = map(X, 1021, 0, 0, 7);
  char y = map(Y, 1021, 0, 7, 0);
 

  Serial.print(X, DEC);
  Serial.print(",");
  Serial.print(Y, DEC);
  Serial.print(",");
  Serial.print(Z, DEC);

    lc.clearDisplay(0);
