Orientation is critical: Make sure that the half-moon indentation at one end of the chip matches that on the socket and PCB. Insert it firmly, as far down into the socket as it will go. |

The total range is about half of a turn. Locate the center position for your particular servo, which will be halfway between its two ends of travel. |
+ | Once you know where center is, point the servo horn in that direction. This orients the output shaft in the correct direction. Then, remove the servo horn, taking care to move the motor shaft as little as possible in the process. | ||
− | + | Now that the servo shaft is centered, we need to place the servo horn at the correct angle. Orient the servo horn as shown: the horn points slightly above and away from the cable. Press the servo horn onto the shaft. Use the small screw from the servo bag to fix the servo horn in place. | |
− | + | Use the two small screws that were not included in the servo bag to connect the servo horn extender to the servo horn. The screws will self tap into the pilot holes in the servo horn. However, if you use the hole in the very tip of the servo, it may split open, so it is better to use two of the other holes. | |
− | + | You can use the holes in the mounting tabs on the servo motor sides to mount part of a toothpick to help hold your servo motor into your pumpkin. Alternately, you can hold your servo motor down with toothpicks anchored entirely above it. If your servo motor sits too low or unevenly in your pumpkin, a scrap of cardboard makes a good leveling surface. | |
