Relay Control

     I've been thinking about a project to control the flash light on the Christmas tree since the Xmas is coming. 

     Therefore, I wrote a program on Arduino that provide 2 way to control the light on the tree. 

     First, use keyboard or Bluetooth of your smartphone to control.

     Second, use buttons to control.

Check out the rough code below: 

void setup()
{ 
 pinMode(2,INPUT);
 Serial.begin(9600);
}

void loop()
{ 
 SericalControl();
}

int relayswitch(boolean status)
{
 if(status == 1)
 {
  digitalWrite(7,HIGH);
  Serial.print("relaystatus = ");
  Serial.print("HIGH");
 }
 else
 {
  digitalWrite(7,LOW);
  Serial.print("relaystatus = ");
  Serial.print("LOW");
 }
 return 0;
}


void SericalControl()
{ 
 if (Serial.available())
 {
  char cmd = Serial.read();
  switch(cmd)
  {
   case '1' :
   relayswitch(1);
   break;

   case '2':
   relayswitch(0);
   break;

  }
 }
}

void ButtonControl()
{
 int bottonCmd = digitalRead(2);
 if (bottonCmd == 1)
 {
  relayswitch(1);
 }
 else
 {
  relayswitch(0);
 }
}
