Electronics Course — From Zero to WiFi-Connected Projects

Learn electronics from scratch with 13 hands-on modules. No prior experience needed — just curiosity and an Arduino starter kit.

Each module builds on the last. You'll start with electricity fundamentals, build real circuits, write Arduino code, add sensors and displays, and finish by connecting your projects to WiFi with the ESP8266.

What You'll Build

  • LED circuits with calculated resistor values
  • An automatic nightlight that responds to ambient light
  • A temperature and humidity display
  • An ultrasonic distance sensor with servo control
  • A WiFi-controlled LED strip you operate from your phone

Beginner Modules

  1. Module 1: Electricity Fundamentals — Voltage, current, resistance, and your first LED circuit
  2. Module 2: Meet the Arduino — Board anatomy, IDE setup, and your first blink sketch
  3. Module 3: Inputs & Outputs — Buttons, sensors, PWM, and the Serial Monitor
  4. Module 4: Logic & Control Flow — Conditionals, loops, state machines, and millis()
  5. Module 5: Power Management — Power sources, voltage regulators, and servo power budgets

Intermediate Modules

  1. Module 6: Sensors Deep Dive — Temperature, ultrasonic, motion, and soil moisture sensors
  2. Module 7: Communication Protocols — I2C, SPI, and UART explained with hands-on wiring
  3. Module 8: Displays & Visual Feedback — Shift registers, LCDs, and OLED screens
  4. Module 9: Sound & Audio — Buzzers, melodies, microphones, and speakers
  5. Module 10: Motors & Movement — Servos, DC motors, steppers, and motor drivers
  6. Module 11: Arduino Nano & Compact Builds — Portable projects and enclosure planning
  7. Module 12: Troubleshooting & Debugging — Systematic problem-solving for electronics
  8. Module 13: Introduction to WiFi — ESP8266, web servers, and IoT basics
