Take photo & save in on SD after color detection

Pixy Software
#1

Hi,
I have CMUcam5 with arduino.
I consider how to take photo and save in on SD card after detection of eg. red color.
Any ideas ? examples ?

Regards,
Karol

Hello Karol,
Pixy does not have an SD card slot to save images. Pixy can send images over USB, however, but the firmware/datarate prevents Pixy from sending raw images over SPI, which is what an Arduino typically uses to talk to Pixy.

Have you considered using a Raspberry Pi? This has an SD card slot and a USB port.

Hope this helps!

Hi Edward
I have arduino installed already in my home as a alarm, weather monitor and some other things - everything connected to my router.
I have separate SD module and I thought that it is not so difficult to take photo and send it to SD card via Arduino. Raspberry is “new platform” for me.
Of course I aways can buy TLL camera or use some other micro camera with motion sensor.
I can’t believe that I can’t use Pixy camera to take photo. :frowning:

Hello Karol,
It’s a good point. Pixy is intended to be used as a vision sensor and not so much a camera that takes pictures. Still, we get several requests for this. We should maybe consider adding!

Thanks for your message. :slight_smile:

Please conside add support for arduino Yun, it has a linux part which can stream usb video direct from pix to its linux part, do it direct on adruino may not allowed as the memory limitations.

Hello John,
Have you tried to compile and install libpixyusb?

I haven’t tried it on Yun, but the steps above should work for most Linux platforms.

Hope this helps!
