Before starting this project, students should be familiar with:
Arduino IDE Basics: Ability to upload code and use the Serial Monitor for debugging.
Basic Component Wiring: Understanding how to use a breadboard and identify VCC, GND, and Signal pins.
Fundamental Physics: A basic grasp of how sound waves reflect off surfaces (the principle behind the UR sensor).
L298N Familiarity: Knowledge of how to connect external battery power to the motor driver while sharing a common ground with the Arduino.
In this hands-on course, students will transition from basic circuitry to behavioral robotics. By building a "Pet Bot," students will learn how to use an Arduino Nano and an Ultrasonic (UR) Sensor to mimic lifelike responses. The robot will be programmed to "see" distances and react—either following its owner or backing away when startled. This course covers the essentials of autonomous navigation, efficient power management using Li-ion batteries, and driving motors through the L298N H-Bridge module.
By the end of this module, students will be able to:
Interface Ultrasonic Sensors: Accurately measure distances and convert sound waves into usable data for the robot's "brain."
Implement Proportional Logic: Program the robot to move at different speeds based on how close an object is.
Manage Portable Power: Safely wire and switch Li-ion batteries to provide consistent current to high-draw motors.
Design Autonomous Behaviors: Create code that allows the robot to make independent decisions without human remote control.
