Hi everyone!
I have a Quiic MP3 trigger and a wav trigger.
I would like to trigger sounds from a photo resistor (like this? https://www.sparkfun.com/products/9088 )
(Basically, I would like to modify an old lan telephone and play a sound whenever someone pick up the phone. So my idea is to put a photo resistor underneath the handset.)
I guess it is possible but I can’t find the answer online.
Can you help please?
Thank you very much.
https://www.sparkfun.com/products/18448 is probably what you’re after 
Be sure to follow the hookup guide on the documents tab, and then just implement the sensor into your phone
It would probably be easier to use the existing hang up switch on the phone. That might also be more reliable in varying ambient light conditions.
^That’s a really good point 
Thank you very much for your answers.
@Brow I had definitely thought of using the the hang up switch and I will work on it but I am not sure yet if every phone I will modify will have this switch.
@TS-Russel, I’ll have a look on this although it seems a bit complicated for me. For instance, I have no clue how to set a define threshold above which a signal is sent from the sensor… https://learn.sparkfun.com/tutorials/qw … ample-code
Where can I get this help? Thank you!!

I’d [follow this guide and modify the code provided to check for a reading with the phone off the hook to generate a digital output that triggers your wav trigger. You will need to figure out what that value is experimentally.](https://learn.sparkfun.com/tutorials/photocell-hookup-guide)
Thanks vey much! I’ll give a try for this as well!
