Arduino C# Microcontroller Programming Course

Lesson 1 • Setting Up the Development Environment

Guides installation of the Arduino IDE, .NET SDK, and required drivers on Windows, macOS, and Linux. You will finish with a verified, connected development environment.

Lesson 2 • Essential Electronics Concepts

Introduces voltage, current, resistance, and Ohm's Law as prerequisites for circuit work. Provides the physics foundation needed for every subsequent hardware section.

Lesson 3 • Safety and Lab Best Practices

Establishes safe handling of components, ESD precautions, and bench organisation habits. Prevents hardware damage and personal injury throughout the course.

Lesson 4 • Arduino Hardware Components

Identifies the Uno, Nano, and Mega boards along with their pins, power rails, and onboard features. Prepares you to select the right board for a given project.

Lesson 1 • Control Flow and Logic

Teaches if/else, switch/case, for, while, and do-while constructs with practical examples. Enables you to write decision-making and repetitive logic in sketches.

Lesson 2 • Debugging Sketches Effectively

Introduces Serial.print debugging, common compiler errors, and logic fault isolation. You will gain systematic troubleshooting skills applicable to all future projects.

Lesson 3 • Data Types and Variables

Covers int, float, bool, char, String, and byte types with memory implications. Correct type selection prevents overflow and conserves limited RAM.

Lesson 4 • Sketch Structure and Execution Flow

Explains setup(), loop(), and the Arduino runtime lifecycle. Connects sketch structure to how the microcontroller executes code repeatedly.

Lesson 1 • Interrupts and Event-Driven Input

Configures external interrupts with attachInterrupt() for responsive, non-blocking input handling. Prepares you for time-critical applications in later chapters.

Lesson 2 • Analogue Input with ADC

Reads potentiometers and sensors via analogRead() and interprets 10-bit ADC values. Connects raw ADC counts to meaningful physical measurements.

Lesson 3 • Digital Output and LED Control

Uses pinMode() and digitalWrite() to drive LEDs and other digital loads. Establishes the output control pattern reused throughout the course.

Lesson 4 • Digital Input and Button Reading

Reads button states with digitalRead() and manages pull-up and pull-down resistors. Introduces debouncing as a critical real-world input technique.

Lesson 1 • Connecting Common Sensors and Displays

Integrates temperature, humidity, and distance sensors plus OLED displays using the protocols above. Reinforces protocol knowledge through hands-on peripheral wiring.

Lesson 2 • Protocol Troubleshooting and Analysis

Uses Serial Monitor output and logic analyser concepts to diagnose communication faults. Builds systematic debugging skills for multi-device systems.

Lesson 3 • UART Serial Communication

Configures hardware and software serial ports for device-to-device and PC communication. Provides the messaging backbone used in most Arduino projects.

Lesson 4 • I2C Protocol and the Wire Library

Explains I2C addressing, master/slave roles, and uses the Wire library to communicate with sensors. Enables connection of multiple devices on a two-wire bus.

Lesson 1 • Hardware Timers and Precise Timing

Configures AVR hardware timers for precise PWM generation and periodic interrupts independent of loop(). Eliminates timing drift caused by blocking code.

Lesson 2 • Watchdog Timer and Fault Recovery

Configures the watchdog timer to automatically reset a hung sketch and log fault events. Improves firmware reliability in unattended deployments.

Lesson 3 • Writing and Publishing Arduino Libraries

Packages reusable sketch code into a proper Arduino library with header, source, and keywords files. Shareable libraries accelerate team development and community contribution.

Lesson 4 • Power Management and Sleep Modes

Reduces current consumption using AVR sleep modes and peripheral shutdown techniques. Critical for battery-powered and remote sensor deployments.

Lesson 1 • Parsing and Displaying Sensor Data

Parses incoming serial strings in C# and displays live sensor readings in a console or WinForms UI. Connects raw hardware data to a user-facing software layer.

Lesson 2 • Sending Commands from .NET to Arduino

Implements a command dispatcher in .NET that triggers Arduino actions such as LED control or motor activation. Demonstrates bidirectional hardware-software control.

Lesson 3 • Logging Data to Files and Databases

Stores sensor readings in CSV files and a local SQLite database from a .NET application. Provides persistent data storage for analysis and reporting.

Lesson 4 • Serial Communication from .NET

Uses System.IO.Ports.SerialPort to open, read, and write data between a .NET app and Arduino. Establishes the primary integration channel for the rest of the chapter.

Lesson 1 • User Controls and Hardware Interaction

Creates reusable toggle, slider, and indicator controls that send commands to Arduino. Encapsulated controls accelerate dashboard development and reuse.

Lesson 2 • WinForms Application Architecture

Structures a WinForms project with separation of serial, UI, and data layers. Clean architecture prevents spaghetti code as dashboard complexity grows.

Lesson 3 • Real-Time Data Visualisation

Plots live sensor streams using chart controls and timer-driven updates in WinForms. Gives users immediate visual feedback from connected hardware.

Lesson 4 • WPF and MVVM for Arduino Dashboards

Builds a WPF dashboard using the MVVM pattern with data binding to live Arduino values. MVVM improves testability and maintainability over event-handler approaches.

Lesson 1 • Firmware Design and Implementation

Implements modular Arduino firmware with sensor reading, command handling, and serial output. Applies all firmware techniques from previous chapters in a unified codebase.

Lesson 2 • Deployment, Demo, and Review

Deploys the complete system, presents a live demo, and conducts a structured retrospective. You will consolidate learning and identify areas for continued growth.

Lesson 3 • Backend .NET Service Development

Builds a .NET background service that manages serial communication, data storage, and REST endpoints. Decouples hardware I/O from the presentation layer.

Lesson 4 • System Architecture and Requirements

Defines functional requirements, hardware selection, and a layered system architecture diagram. A clear architecture prevents scope creep and guides all implementation decisions.
