Bro kya hum fire fighting robot main flame sensor ki jagah smoke detector used kar sakte hai kya???

[@shreshthgupta1134]

sir when i brought smoke near sensor value is increasing

[@mohamedsameerah1383]

I have a doubt y arduino... Without that u can do rgt... Bcoz same work smoke detector does

[@marinerankitkushwaha4178]

nice dude

[@arduinoprojets4718]

Give them code as long as you have it will be better

[@sandnyapatil3215]

where did u get the code from?

[@lelandtsnyder9684]

Example code comes with the Arduino SDK kit which is free to download. A quick google should lead you to it.

[@fadilabadaoui6553]

What is the program you instal in the laptop that runs arduino code for a smoke detector please ?

[@Nii_Alpha]

AnalogReadSerial
Reads an analog input on pin 0, prints the result to the Serial Monitor.
Graphical representation is available using Serial Plotter (Tools > Serial Plotter menu).
Attach the center pin of a potentiometer to pin A0, and the outside pins to +5V and ground.

// the setup routine runs once when you press reset:
void setup() {
// initialize serial communication at 9600 bits per second:
Serial.begin(9600);
pinMode(13, OUTPUT);
}
// the loop routine runs over and over again forever:
void loop() {
// read the input on analog pin 0:
int sensorValue = analogRead(A0);
// print out the value you read:
Serial.println(sensorValue);
