-OK, you've [[wiki:​v2:​Assembling_pantilt_Mechanism|assembled the pan-tilt mechanism]] and it looks cool, but it would look even cooler if it moved. One nice thing is that you don't need a battery to move the pan-tilt -- the pan-tilt can use the USB cable for power. ​ **The USB cable that came with your Pixy2 is recommended** for powering your Pixy and pan-tilt. ​ But **as long as the cable is 4 ft or shorter** (3 ft is common.) If you use a longer cable, there can be up to 1 volt of voltage drop along the cable, which is fine for Pixy, but the servos will malfunction. Also, before you run the pan-tilt demo, go ahead and [[wiki:​v2:​Teach_Pixy_an_object|teach Pixy an object]] if you haven'​t already.+OK, you've [[wiki:​v2:​Assembling_pantilt_Mechanism|assembled the pan-tilt mechanism]] and it looks cool, but it would look even cooler if it moved.

 We should also mention that the pan-tilt base needs to be anchored to the table somehow before running the demo.  Attaching your pan-tilt to an Arduino is sufficient. ​ Otherwise, you might try placing the pan-tilt base between two books. ​ If you don't anchor the base, the base will tend to rotate under Pixy, leaving Pixy more or less stationary (and we want Pixy to move/​rotate!) We should also mention that the pan-tilt base needs to be anchored to the table somehow before running the demo.  Attaching your pan-tilt to an Arduino is sufficient. ​ Otherwise, you might try placing the pan-tilt base between two books. ​ If you don't anchor the base, the base will tend to rotate under Pixy, leaving Pixy more or less stationary (and we want Pixy to move/​rotate!)

In particular, select **Program➜pan\_tilt\_demo**. If you're running PixyMon, you can run the demo (or any other program) at any time by selecting it in the **Program** menu.

 Pixy should then track your object and plot the detected objects in the video window. Yay!  Note, Pixymon will switch to a block-only view, so the video window will turn black except for what Pixy is detecting (shown as rectangular blocks). ​ The pan-tilt demo switches to this view because it allows Pixy to process at maximum framerate (doesn'​t slow Pixy down.) ​ Pixy should then track your object and plot the detected objects in the video window.
