Overview

This Arduino code controls a robot equipped with an Arduino Uno, an ultrasonic sensor (HC-SR04), and four DC motors (AFMotor library). The robot's movements are determined based on measured distances in the front and on the sides. The main functionalities include stopping the robot, moving it forward and backward, and turning it left or right.

Functions

2.1 Stop (dung())

Stops all motors, displaying "DUNG" on an LCD.

2.2 Move Forward (tien())

Moves the robot forward with adjustable speed.

2.3 Move Backward (lui())

Moves the robot backward with adjustable speed.

2.4 Turn Left (retrai())

Turns the robot to the left.

2.5 Turn Right (rephai())

Turns the robot to the right.

Distance Measurement

1. Front Distance (distancefront()): Measures the distance in front using the HC-SR04 sensor.

2. Side Distance (distanceside()): Measures the distance on the side using the HC-SR04 sensor.

The main loop continuously measures distances, displays the status on an LCD, and controls the robot's movements based on button input. The code provides flexibility for customizing motor speeds and distance thresholds to suit specific project requirements.
