method of detecting colour - Electronic Circuits Projects Diagrams Free

Hi

Im looking into a method of detecting the colour of a small bead and distinguishing if it is one colour or another, this will them be fed into a microcontroller as a digital signal.

Is a light to voltage converter the device i should be looking at?

I had a TAOS TSL257 RS no 642-4430 in mind...

Any ideas

PICAXE sells this:

If you want your own lens setup (or none at all), you can also look for the TAOS TCS230 which is the colour sensor IC used in this thing.

You could also look up "M&M-sorter".

Have a look at this one:
SparkFun Electronics
or mounted on a breakout board:
SparkFun Electronics
and still about the size of a quarter.
they also give some example source code for common processors.
