Making A Metronome - Part 2

The video tutorial demonstrates the construction of a box with moving parts, focusing on the assembly of acrylic pieces and the use of a limit switch. An initial attempt to link two boxes using a wooden piece fails due to insufficient torque. The solution involves using Lego pieces for successful interaction. The video concludes with an invitation for questions and links to resources for building a similar project.

What material did the teacher eventually settle on for the linkage, and why?

What was the teacher's reaction to the final solution for the project?
