I developed this project for those who enjoy working with Proteus. I created a custom component called "PIANO", which you can easily add to your Proteus library and use in your future projects. In the video below, I show you step-by-step how to add the PIANO component to Proteus and how to use it with a simple Arduino code. The code is taken from the tutorial linked below. You can also download the complete Proteus project file to test the setup directly. 📽️ Watch the video guide: https://youtu.be/GS7PF2pWQfk 📁 Download Proteus project file: https://drive.google.com/drive/folders/1DmQW8gklVSWld-mt7qZbTgiFOUHL2cBq?usp=share_link 🔗 Arduino code (from tutorial): https://technoreview85.com/piano-arduino-uno-nano-easy/ Note: The Arduino code is from an external tutorial. I reused it to demonstrate the use of my custom “PIANO” component.
