ROBOTICS PROJECTS [ LINE FOLLOWING ROBOT ]
Step 1: COMPONETS REQUIRED Hardware: Arduino board (Uno or Nano) Motor driver shield (e.g., L298N) DC motors (2) Motor driver IC (e.g., L298N) Line sensors (2) Breadboard Jumper wires Battery (9V or 12V) Battery connector Chassis and wheels Software: Arduino IDE Step 2: Understanding the Circuit Power Circuit: Connect the battery to the motor driver shield. Connect the motor driver shield to the Arduino. Motor Control Circuit: Connect the motor driver pins to the Arduino's digital pins. Connect the motor terminals to the motor driver. Sensor Circuit: Connect the line sensors to analog pins on the Arduino. Use resistors (e.g., 10k ohms) to create a voltage divider circuit for the sensors. Step 3: Write the Arduino Code C++ # define leftMotorPin1 5 # define leftMotorPin2 6 # define rightMotorPin1 9 # define rightMotorPin2 10 # define leftSensorPin A0 # define rightSensorPin A1 void setup () { pinMode(leftMotorPin1, OUTPUT); pinMode(l...
