An Arduino-based maze-solving robot using 3 ultrasonic sensors, an L293D motor driver, and 2 DC motors. The robot detects obstacles, makes navigation decisions, and autonomously traverses mazes.
Connect the VCC and GND pins of the ultrasonic sensor to the 5V and GND pins of the Arduino board, respectively. Connect the TRIGGER pin of the ultrasonic sensor to digital pin 8 of the Arduino board.
