How Do You Play Mp3 When Photosensor Detects Camera Flash?

Skip to comments   Jump To End

I'm going to be buying the ez robot kit and using a 10" windows 7 tablet to run the system which will be attached to the robot.

Everytime the camera flashes I want the robot to say something cheesy like work it you look sexy smile you're such a tease etc.

What would be the easiest way to accomplish this and where would I get a photosensor? I know I can buy them for cameras, but not sure if the photo studio kind would work wtih the ez-robot kit.

Or perhaps there is a way to integrate it into the PC so the PC is doing the triggering and processing via a script like autohotkey.com perhaps a usb to serial adatper cable hooked into the sensor that opens a random mp3 file, that sounds way too complicated to program confused

anyways looking for the easiest way, I dont' care if it is too expensive.

There are a few ways to do it.

One way would be to fit a photosensor, connect it up via the ADC port so that when the light is bright it returns either a high or low figure (depending on which way round the sensor works). Not a clue which sensor to use but someone else may do.

Then have an EZ-Script to read the ADC port and play a random MP3 when it's detected it's high. Something like;


:start
ADC_Wait(adc0, higher, 200)
MP3TriggerPlayRandomTrack(D0, 38400, 1, 10)
Goto(start)

Bearing in mind the code is very crude and not well thought out at all. It assumes the sensor is on ADC0, a flash causes the sensor to read >200, the MP3 trigger is on D0 and has 10 tracks on it.

most photo sensors has a analog output,plus very easy to make and add. on the autokey,on a project someone else made ,he has hotkey example will find his post.

trying to find a usb adapter to use a photo sensor going to be very hard,main reason it will need a cpu and then a c++ program and DLL file to make API calls to it.

second when a camera flashes the sensor wont have enough time to to turn on MP3

so what you need is to tap in the circuit before it flashes,or if the camera has a second flash that takes the photo.

best part is where is recognizes people ,it where you make tap point.

i guess i can buy the camera interface for the camera,and hack it for a connection

Just an idea which you may or may not like but the camera control can detect faces and that can run scripts... so when it sees someone it'll play a sound...

Add in an EZ Kit camera along side the camera taking photos, or any camera (doesn't need to be the EZ kit one), run a script which plays a random mp3 on face detection.
