Block Diagrams

Hardware

A hardware block diagram, showing a DC power source powering a dual H-bridge motor driver, an Arduino Nano microconroller, two magnetic hall effect encoders, and four infrared sensors. The encoders and sensors feed information to the microcontroller. The motor driver powers two DC motors connected to a pair of wheels.

Software

A software diagram for a maze-solving robot in the form of a flowchart. After the robot is placed in the maze, it resets its memory before starting a floodfill algorithm. The robot starts assuming there are no walls in the maze, and attempts to move toward the center. If it encounters a wall, it recalculates the distance to the center for its location and adjacent locations. It then moves closer to the center of the maze, and repeats the process until the center of the maze is reached.
