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

[@mohamedsameerah1383]

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

[@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 ?

[@shreshthgupta1134]

sir when i brought smoke near sensor value is increasing
