In this first session, we began by brainstorming together to define the main features of our clock. We analyzed the different types of mechanism possible and discussed the components required, such as motors, displays (analog or digital), and structural elements. Once we had validated our idea, we set about realizing it by selecting the first components and drawing up an initial assembly diagram.

In the second session, we tested the technical feasibility of the project by switching to Arduino programming. The aim was to check whether our system could function correctly by controlling the needle's movements via a microcontroller. At first, we used servo-motors, but after several tests, we opted for stepper motors for better precision and synchronization. This step enabled us to identify certain adjustments to be made to optimize clock operation.
