Switching Button

by J.B. Wylzan

Project 11: The Switch

This project teaches how to turn on and off any of your first 10 projects with a switch button.



Hardware:
LEDs
resistors
switch button
wires
breadboard
computer cable
Arduino UNO

Block Diagram:


image designed by Fritzing


Actual Assembly:  

Procedure:
1. Use the same prototype as shown above
2. Run the Arduino Interface
3. Select File > New
4. Copy Code #11  below
5. Paste Code #11
6. Click File > Save
7. Click Verify
8. Click Upload
9. Activate Project Breaker by pressing a switch

Code # 11:  
/* 
    iHackLab The Switch 
    powered by Arduino
    sketched by J.B. Wylzan
    modified by Lawsinium

  Executes Project Breaker when a switch is pressed 
  Turns On Led (#8) when switch is released.
  Initializes values on certain variables.
  This example code is public domain. */
    
//declare variables/constants

int y = 1000;           // y is a variable with a certain value = 1000
int z;                        // z is a variable with uncertain value

void setup() {
  pinMode(3, INPUT);
  pinMode(4, OUTPUT);
  pinMode(5, OUTPUT);
  pinMode(6, OUTPUT);
  pinMode(7, OUTPUT);
  pinMode(8, OUTPUT);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);
}

void loop() {
 z = digitalRead(3);                               // input action: Press or Release ?
 if (z == 0)                                               // if button is in release mode; z == 0 
 {
 digitalWrite(8, HIGH);                          // led#8 turns ON

  digitalWrite(10, HIGH);                   // turn the LED on
  delay(y);
  digitalWrite(6, LOW);                     // turn the LED off
  digitalWrite(10, LOW);                   // turn the LED off
  
  digitalWrite(5, HIGH);                    // turn the LED on
  digitalWrite(11, HIGH);                  // turn the LED on 
   delay(y);
  digitalWrite(5, LOW);                    // turn the LED off
 digitalWrite(11, LOW);                   // turn the LED off  

  digitalWrite(4, HIGH);                    // turn the LED on 
  digitalWrite(12, HIGH);                  // turn the LED on
  delay(y);
  digitalWrite(4, LOW);                      // turn the LED off 
  digitalWrite(12, LOW);                    // turn the LED off 
      // **procedure Breaker ends** 
  }
}

/*    End of Program       */



Serial Monitor Test:
//replace the button with any sensor e.g. motion sensor

byte sensorPin = 3;
byte ledPin= 13;
void setup()
{
pinMode(sensorPin,INPUT);
pinMode(ledPin,OUTPUT);
Serial.begin(9600);
}
void loop()
{
byte state = digitalRead(sensorPin);
digitalWrite(ledPin,state);
if(state == 1)Serial.println("Warning! Intruder!!!!");
else if(state == 0)Serial.println("No one!");
delay(500);

}
