In the setup() function we set the pins were the LDR are connected as INPUTs and position the servo motor at 90° then wait for a 2 seconds before the code execution inside the loop(). In the loop() we ...

For instance, the Serial Servo Raspberry Pi HAT offers multiple powering options, four Serial Servo connectors, four programmable buttons, an on/off switch, and a 1.14” TFT Display for status ...

Very nice project. As described in the video, for servo motor v dumb stepper, servo motor is more efficient and servo motor won’t miss steps, or at least not without being able to provide a warning.
