+# Smart Fishing Boat

+## Description
+
+This project is a Bluetooth-controlled smart fishing boat built using an STM32 microcontroller programmed in Rust.  
+The boat can be controlled using a Bluetooth HC-05 module. It uses two independent DC motors for movement and a servo motor to open a bait container and release the fishing bait.
+
+## Motivation
+
+I chose this project because I wanted to combine embedded systems with real-world robotics.  
+A fishing assistant boat is a practical and fun application of microcontrollers, motor control, and mechanical actuation.
+
+## Architecture
+
+![Architecture Diagram](./diagrama.svg)
+
+The system is composed of the following main components:
+
+- STM32 microcontroller (main control unit)
+- Motor driver module (controls 2 DC motors)
+- Two DC motors (propulsion system)
+- Servo (catapult mechanism)
+- Power supply (battery system)
+
+### How they connect:
+
+- STM32 sends PWM signals to motor driver → controls movement
+- STM32 controls servo signal → triggers catapult
+- Battery powers all components through power distribution circuit
+
+## Log
