Arduino Step-by-step Projects

Build 25 Projects

My step-by-step course to get you building cool Arduino projects,
even with no prior experience!



Project Modules

This Arduino Course is a compilation of 25 projects divided in 5 Modules that you can build by following clear step-by-step instructions with schematics and downloadable code.

Module #1: Lights and LEDs

In this module you’ll build several projects using lights: LEDs, lamps and RGB LED strips. These are good projects to practice controlling outputs and reading inputs from buttons, potentiometers and sensors. You’ll build simple projects like a traffic light system and more advanced projects like a night security light with a lamp and relay.

  • Traffic Lights
  • LED Brightness on LCD
  • Light Sensitive LEDs
  • Remote Controlled LEDs
  • Monitor Stand with Ambient Light
  • Night Security Light

Module #2: Sensor Projects

This module is all about getting data from sensors with the Arduino. Sensors included in this module’s projects are: ultrasonic sensor, temperature and humidity sensor, barometric sensor, smoke/gas sensor and sound sensor. Projects in this module also cover subjects such as data logging, time and date display using a real time clock (RTC) module and using the OLED display to show information.

  • Smoke Detector Alarm
  • Parking Sensor
  • Arduino Weather Station (AWS) with Temperature, Humidity, Pressure, Date and Time
  • Weather Station – Data Logging to Excel
  • NEW - Request Sensor Data via SMS

Module #3: Sound Projects

This module includes projects related with sound. You’re going to learn how to use a sound sensor to detect sound and how to use a buzzer to make sound effects.

  • Pseudo-Theremin
  • Sound Sensitive Lights
  • Piano Keyboard

Module #4: Creating Applications

In this module you’ll create applications for your Arduino. You’ll use a bluetooth module and an ethernet shield to build android apps and a web server to control outputs and read inputs and a smartphone notification system. A really cool project you’ll build in this module is controlling a relay with voice commands using an Android app.

  • Bluetooth Android App
  • Voice Controlled Relay App
  • Arduino Ethernet Web Server (Relay + Temperature)
  • Shake Controlled LED
  • Intruder Detector with Notifications

Module #5: Miscellaneous Projects

This module includes subjects covered in all modules to create fun and interactive projects. You’ll create robots, build a stopwatch, create a memory game and build an electronic dice roller that you can actually use when you play board games with your friends.


  • Arduino Stopwatch
  • Electronic Dice Roller
  • Memory Game
  • Light following Robot
  • Bluetooth Remote Controlled Robot
  • NEW - Time Attendance System with RFID

Who is this for?

I believe this course is perfect for anyone that loves electronics, open-source hardware and software, and of course the Arduino board.

If you’re a beginner don't worry, I’ll start from the very beginning and you’ll learn everything you need to know to complete all projects presented.
