Plays standard Midi files.

An update of the older version of the keyboard. Now it doesn't require switches on your breadboard, you can use your pc keyboard.

As a musician and music passionate, this little Keyboard is my first (but not last) Arduino project. Hope you have fun with it :)

This project uses an Arduino, a drawn keyboard using lead pencil, a paper, and a speaker.

This is a project of Radio Receiver LW/MW/SW Stereo FM with RDS, using Arduino Nano, Si473x Radio IC and 1.8in TFT color display ST7735.

This radio was made by using TEA5767 module radio.
