Diwali Special

Winter is Coming...festival decorations are everywhere.

One of the gadgets that can be found everywhere are led light diya . They are cheap, clean and not as dangerous as real diya.

Let's start it.....

What we need for this DIY is a

• Diya
• Leds
• Arduino uno
• Gas sensor
• General purpose Pcb
• Wire
• Lm 324 or 358
• Photodiode
• Resistances 330 ohm , 10k
• Potentiometer 10k
• Hot glue gun
• A box
• Soldering iron
• Screwdrive

STEPS are :

1. Takes some Yellow Leds and glue it on Diya with the help of hot glue gun.
2. Now connect the all leds in parallel (positive to positive and negative to negative) with the help of soldering iron.
3. Than I drilled the hole for I.R SENSOR and GAS SENSOR wire.

I used two sensors :

1. one is I.R SENSOR with the help of I.R SENSOR. I am able to operate my DIWALI SPECIAL DIYA with any I.R remote (T.V, A.C).
2. second one is GAS SENSOR.

WATCH MY VIDEO if you want to know why i am using Gas sensor in my instructable.

Take a box and cut it from the bottom portion and glue it on base surface of Diya

int ledPin = 3; // choose the pin for the LED
int switchPin =4; // choose the input pin (for a pushbutton)
int val = 0; // variable for reading the pin status
int counter = 0;
int currentState = 0;
int previousState = 0;
void setup() {
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(switchPin, INPUT); // declare pushbutton as input
pinMode(A0, INPUT);
}
void loop(){
int pot_value = analogRead(A0);
val = digitalRead(switchPin); // read input value
if(pot_value>=180)
{
digitalWrite(ledPin, HIGH);
 }
else if(pot_value<=180&&pot_value>=150)
{
digitalWrite(ledPin, LOW);
 }
if (val == LOW) { // check if the input is HIGH (button released)
currentState = 1;
}
else {
  currentState = 0;
}
if(currentState != previousState)
{
if(currentState == 1)
{
counter = counter + 1;
}
if(counter%2==0)
{
digitalWrite(ledPin, HIGH);
 }
else
{
digitalWrite(ledPin, LOW);
}
}
previousState = currentState;
delay(250);
}
