I am using the Pixy with Arduino to do a color ball follower robot. The Arduino doesn’t seem to supply power enough to the i2c because the Arduino disconnects from my PC intermittently. I tried to use an external power 12vdc supply to the Arduino to attempt to sustain any voltage drops and it worked at first. However, after a few minutes, a smell of burnt semiconductor came out from the Pixy. No apparent damage is visible. I connected the Pixy to my PC to test and the Pixymon is able to detect. The image however was very poor, dark and monochromatic. No settings fixed it and the Pixy seemed blind for good. It cannot process signatures. The Arduino is still functional after the incident.
Has anyone experienced this and has anyone managed to fix it? What could have caused it? I cannot explain what happened because the output of the Arduino to the i2c should be regulated 5 vdc.
I suggest to put a warning on Pixy products to avoid this accident and instead get power directly from the J1 on the Pixy.
Any thoughts, ideas or explanations are highly appreciated. Thanks guys.
