  • pir sensor timer - Programming - Arduino Forum
    Im having a problem setting up a timer with a pir sensor what im aiming to do is to set it up so if the sensor detects motion it comes on and sets a timer to turn off, moving forward if the timer is not up yet and it detects motion again the timer will reset so the light can stay on example: motion detected - light turns on 45 second timer is started at 15 seconds left motion is detected
