This image displays a collection of electronic and mechanical components commonly used for building small, Arduino-controlled robotic projects, particularly wheeled vehicles or line-following robots. The key elements include:Arduino Uno Microcontroller Board: This blue board serves as the "brain" of the project. It's a programmable platform that can read sensor inputs, process data, and control the output to motors and other actuators. USB Cable: Used to connect the Arduino to a computer for programming and to provide initial power for development.L298N Dual H-Bridge Motor Driver Module: This blue board with several integrated circuits acts as an interface between the Arduino and the DC motors. It allows the Arduino's low-power signals to control the speed and direction of the motors, which require more current.DC Motors with Gearboxes (TT Motors): The four yellow and black units are small DC motors paired with reduction gearboxes. The gearboxes increase the output torque and reduce the speed, making them suitable for driving the wheels of a robot.Wheels: The four black rubber tires with yellow hubs are designed to fit onto the shafts of the TT motors, providing traction for movement. Infrared (IR) Line Follower Sensors: The three blue boards with the black sensor units are used to detect lines (typically black on a white surface). They work by emitting infrared light and measuring the intensity of the reflected light. This information can be used by the Arduino to guide a robot along a defined path. 9V Battery: This rectangular battery provides a portable power source for the project once it's no longer tethered to a computer.9V Battery Clip Connector: This connects the 9V battery to the rest of the electronic circuit.Mini Breadboard: The white board with numerous holes allows for solderless prototyping of circuits, making it easy to connect components temporarily for testing and experimentation.Slide Switch: This red and black component is a simple on/off switch to control the power to the circuit.Jumper Wires: The assortment of black and white wires is used to make electrical connections between the different components on the breadboard and to the Arduino.Cable Ties: These white plastic strips are useful for organizing and securing the wiring, preventing tangles and ensuring a neater assembly.Overall, this collection provides the fundamental components needed to build a basic mobile robot capable of autonomous movement, potentially following a line using the IR sensors, all controlled by the Arduino microcontroller and powered by a 9V battery.
