CMUcam5 Pixy pan tilt mount with headlight mount.Pan tilt unit pictured is from Adafruit. The pan tilt mounting plate has been modified as shown in the Pixy Pet Robot tutorial found on Adafruit. Headlight 3 LED and reflector unit came from a 27 LED Portable Worklight/Flashlight (Harbor Freight). Tip, the LED unit may be too much to be controlled by an Arduino pin, I am controlling the headlight from an Adafruit Motor Control Shield. Use a current limiting resistor sized for the battery voltage you are using.
