Task 5 - Make a Simple Colorful Obstacle Avoidance Alphabot with RGB and display condition of Alphabot in OLED Display

Task

Make a Simple Colorful Obstacle Avoidance Alphabot with RGB and display condition of Alphabot in OLED Display

Functions To Do

1. Ultrasonic Obstacle Detection
   • If an obstacle is ≤ 20 cm, the robot stops, turns right (with a beep and red LEDs).
   • If the obstacle is 20–35 cm, it moves forward cautiously (yellow LEDs).
   • If no obstacle (> 35 cm), it moves forward freely (green LEDs).
2. Motor Control
   • Functions for forward, backward, left, right, and stop.
3. Visual & Audio Feedback
   • RGB LEDs (NeoPixel) change color based on distance (red/yellow/green/blue).
   • Buzzer beeps when avoiding obstacles.
   • OLED Display shows distance and robot status.
