RED LED MOVING SIGN HOW TO

If it goes above the threshold the green led will turn off and the red led and the buzzer will turn on. Answer (1 of 7): I even replaced with new battery, it doesnt stop flickering the light and i tried reinstalling the drivers also but that doesnt even help. If it stays in the threshold value the green led will be on while the buzzer and red led will be off. After that, it starts the loop, in the loop, there is 2 possible outcomes: 1-it stays in the threshold value 2- it goes above the threshold value.

I created this gas sensor because of multiple reasons:ДЎ- I had to do a school project in which you use the Arduino Uno and upload it to the project hub.Дў- I thought that the smoke sensor is a good project idea as it has the potential to save or help livesДЈ- I had found how to make the code and I thought it very easy.ДЇirst, the code gets indicates values and pins then it indicates the threshold value of the smoke (it is the value that if the sensor senses above it start to alert the person that there is smoke).Then it sets up outputs and inputs.

This idea is very helpful and is used on a daily basis with the smoke alarms that a lot of people have in their houses and I tried recreating that with an Arduino there are also other reasons listed below. The alert just shows a red led and starts beeping. so the sensor has a threshold value (the threshold value is around the amount of smoke in there is a fire) in that if it goes above it starts alerting people in the vicinity. This gas sensor uses a MQ-2 gas sensor to indicate if there is gas in the area.
