What Is Mechatronics?
Mechatronics is the blend of moving parts, sensors, simple chips, and basic computing. It means putting together circuits, basic programs, and small motors. This mix lets you build devices that work by themselves. Mechatronics has been taught since the 1960s. Today, it plays a role in smart devices and home systems.
