Turn on led when I receive an SMS

Hello, I need your help, for my project.

I want to turn on LED when I receive an SMS on my smartphone. Is this project realisable ? I’m a beginner, I search for a similar project on this forum but I did not find it.

I’m sorry for my bad english :frowning:

Thanks for your answers.


Sure it is. But you need to write some software for your smartphone :slight_smile:

I thought I would use the phone ring with bluetooth to turn on the led.
For example : When the arduino detects the ringtone, it turns on the led

Just build an app that switches on the flashlight upon receipt of SMS. That'd be the easiest way to do this. No extra hardware needed even.

This is easiest but its not what i need.

This project is for a group of persons in a workshop. The light must be seen by all the workers.

The flashlighty LED in my phone is much brighter than the a typical LED used in my Arduino projects...

OK, then start with the above, tape an LDR to the LED of your phone, have that switch a relay (can be as simple as adding a pull-up or pull-down resistor to create the appropriate signal for a relay module), connect that super bright light to that relay output. You can add a siren and maybe have it set off some fireworks to ensure attention from everyone in range.
