How Your Robot Works (Kid-Friendly Breakdown):

🟢 Brain (Arduino Uno): Reads the Ultrasonic distance sensor 25 times per second using Pins D2 & D3.

🟢 Muscles (L298N / TB6612 Driver): Takes weak 5V signals from Arduino Pins D5 & D6 and sends strong 7.4V battery power to spin the 4 wheels!

💡 Pro Tip for Kids: Always connect the Battery GND (-) wire to BOTH the Motor Driver GND and Arduino GND so signals have a return path!

5V & GND Isolation: 🟢 PASS No short circuits between 5V and GND rails.

Timer PWM Pins: 🟢 PASS Motors wired to ~D5 and ~D6 with hardware PWM speed control.

Motor Power Rule: 🟡 IMPORTANT Never power motors directly from Arduino 5V pin! Use the 7.4V Battery into L298N VMS.

Autonomous Ultrasonic Blind Stick & Rover

1. Aim & Real-World Problem Solved

To design an affordable autonomous obstacle-detecting robot using an Arduino Uno R3 and HC-SR04 ultrasonic transceiver that prevents collisions and assists navigation.

2. Apparatus & Arduino Pin Connections

• Arduino Uno R3 (ATmega328P), HC-SR04 Ultrasonic Sensor (Trig → D3, Echo → D2), L298N Motor Driver (PWM → D5, D6), Piezo Buzzer (D8), 7.4V Li-ion Battery.

3. Formula & Scientific Principle

Sonar Time-of-Flight (ToF): Distance (cm) = (Speed of Sound 0.0343 cm/µs × Echo Pulse Duration µs) ÷ 2.
