This free online course covers the steps in making an Arduino=based piano, Morse code generator and RGB LED lamp.

Imagine being able to make your Arduino-based piano and feeling the thrill of it. Or possibly a Morse code generator and a multicolor RGB LED lamp? This course instructs you how to build all three products in a matter of hours by employing easy approaches. First, you'll learn how to create your electronic piano by connecting seven push buttons, a few resistors, a buzzer, and an Arduino board. We also explain how to program the musical instrument and control its tones.

Next, we investigate the concept of Morse Code, including its background and practical applications. After that, we uncover the pieces needed to assemble your first Morse Code Generator powered by Arduino. Subsequently, you will learn how to design a circuit schematic using Fritzing software. We then discuss setting everything up by writing the code that will convert any alphabet or number into Morse code equivalent beeps by buzzer or speaker.

Lastly, instructions for constructing an Arduino Multicolor RGB LED lamp controlled over Bluetooth round off the course. We describe each necessary component, including an RGB LED, a USB cable and an HC-05 module, and how to pair the assembled prototype with an application on a smartphone through Bluetooth. This course will help you start or expand your electronic device inventory. So, why delay? Sign up now!
