In this final section of the build, you will be routing your gripper servo wire to the ESP32 and running your final checks to make sure the arm is built properly.

• Assembled Robot
• Extension Wires
• ESP32

1. Weave the gripper servo wires through the dogbones along the arm until you run out of length.
2. Attach the extension wires making sure to match the colors.
3. Plug the wires into D33 on the ESP32 making sure they are perpendicular to the ESP32 and the brown wire is closest to the ESP32.
