Move a webcam between adjustable positions on a track. The track is built by plugging together several base objects that are designed to fit together seamlessly. Movement is driven by a stepper motor, which is expertly controlled by an Arduino Nano microcontroller. The parameters for the gear were carefully calculated with the rack and pinion calculator available online at https://www.otvinta.com. Secure two pins firmly in place to fix the Motorcarrier to the Carrier. Electronic parts list: * Stepper motor Nema 7 * Arduino Nano * A4988 stepper driver * Two Light barriers NY-010 from AZ-Delivery * Three LEDs for added visibility * Three Resistors with a value of 330 Ohms each * One Capacitor with a capacity of 100 uF * Power supply units, one at 5V and the other at 9V * Two Connectors for power supplies to keep things organized
