RC Boat

<h2>Project Overview</h2> <p>Build a remote-controlled boat with Arduino, motor driver, and servo for steering.</p> <h2>Bill of Materials (BOM)</h2> <ul> <li>Arduino board</li> <li>RC transmitter and receiver</li> <li>motor(s) with propellers</li> <li>motor driver (like L298N)</li> <li>rudder with servo</li> <li>waterproof chassis/hull</li> <li>and power source (battery pack).</li> </ul> <h2>Circuit Diagram & Component Arrangement</h2> <p>Follow the wiring diagram below. Each component connects to specific pins on the microcontroller. Use a breadboard for prototyping and ensure all connections are secure before powering on.</p> <p><strong>Wiring Summary:</strong> The RC receiver is connected to the Arduino's input pins. The Arduino reads the signals and controls the main motor(s) via a motor driver and the rudder's servo motor to steer the boat.</p> <h2>Step-by-Step Procedure</h2> <ol> <li><strong>Step 1 - Prepare Components:</strong> Gather all components from the BOM. Inspect for damage and verify ratings.</li> <li><strong>Step 2 - Breadboard Layout:</strong> Place the microcontroller on the breadboard. Arrange components for clear wiring paths.</li> <li><strong>Step 3 - Power Connections:</strong> Connect VCC and GND first. Ensure proper polarity for polarized components.</li> <li><strong>Step 4 - Signal Wiring:</strong> Connect sensors and actuators per the wiring table. Double-check pin assignments.</li> <li><strong>Step 5 - Upload Code:</strong> Connect USB, load the sketch, and upload. Verify serial output if applicable.</li> <li><strong>Step 6 - Test & Calibrate:</strong> Power on and test each function. Calibrate sensors if needed.</li> <li><strong>Step 7 - Enclosure (Optional):</strong> Mount in a 3D-printed or custom enclosure for durability.</li> </ol> <h2>Safety Notes</h2> <ul> <li>Always disconnect power before making wiring changes.</li> <li>Use appropriate eye protection when soldering.</li> <li>Adult supervision is required for makers under 16.</li> <li>Do not exceed voltage ratings of components.</li> </ul>
