Dear Arduino friends.
After this summer, my school exam starts.
For this exam I need build and part of an production line, the goal of the line is: To put little glass bottle's on an conveyor belt, fill them with liquid and do some tests.
Now my part of this line is to check if the liquids inside are the right colors. (I thought to do this with an simple RGB sensor)
Here is my problem: The Reflection on the glass is to big so i don't get any good measurements.
Now i hope if you guys can help me design the perfect sensor.
Im using now and simple LDR and one of the 3 RGB leds.
So i got 3 terminals, (It would be even better to got this in one terminal)
Also one rule of the exam i need to build it myself.
Please help me out,,
Jeffrey
