My problem is the ability to trigger actions on the color cards supplied with the unit. By this I mean, going over a color that I programmed in the Scratch program and trigger an event like “Speak out the color”.
I laid all the card side by side and had the RVR go over them at speed 50. The only color that triggers the event 100% of the time is the red one, the others maybe 1 out of 10. I made a snapshot of the color sensor recording when it was passing over green, purple, yellow,green and finally red. I can see that they are all detected but only the red as a strong pulse.
There was also a large lag between the red color card and the event. I did a test at speed around 50 and the RVR was way pass the color card, but this may be another issue.
Here are some info:
This info was sent to the support group.
The sensor is clean and without scratch
The white LED underneath is lit when going over all the cards
The lighting in the room is good
All the events are programmed with their specific color using the cards.
I have pictures of the sensor, card setup and color detection pattern snapshot.
If someone had this problem or knows how to resolve it please contact me.
