The HC-05 Bluetooth module is a versatile and cost-effective solution for adding wireless control capabilities to projects like the micromouse. It operates as a serial communication interface, enabling the micromouse to be remotely controlled via Bluetooth technology. The module can be configured either as a primary or a secondary device, allowing for flexible deployment in various robotic applications. By integrating the HC-05 module, the micromouse can receive commands from a smartphone, tablet, or computer, facilitating maneuvers and navigation through a user-friendly interface. This setup not only enhances the interactivity of the micromouse but also expands its potential use in complex environments and mazes, where direct line-of-sight control may not be feasible. With the HC-05’s reliable connection and range, users can precisely control the micromouse’s movements, adjusting its speed and direction with ease.
