Pixy doesn't remember

Hi

Am working with colour codes, when I teaching a pixy to detect some colours, it’s working well but when I turn the power off then start, a pixy doesn’t remember and pick up anything!

my pixy is CMUcam 5.

regards

Hi Mohanad,
Are you powering your Pixy through batteries? A few users have reported that their battery powered setup can cause Pixy to lose signatures when the battery power gets too low (brown out). This can be caused by a poor power setup, such as using the Arduino to power Pixy instead of the other way around. There are pointers for powering your Pixy here:
