I need to detect a color from close distance on demand (more or less accurately). Should I use a RGB Sensor or just use a USB Camera? What would be easier to implement?
I can take a low resolution snapshot from the camera and get RGB value random 500 or so pixels. Not so much of processing… Unless there is already a sensor with netmf driver.
Registered and downloaded the driver. Looks like the sensor itself would work for me if it wasn’t I2C…
What is the max wire length that would work reliably with I2C?
I’ve not had a look at the differences between chips but GHI did have a color sense module until recently so you might have been able to use that source as a starting point.
