LapPiano

About This Project

This initiative centers on creating a digital piano controlled through a laptop and Arduino microcontroller. The creator identified a usability challenge: the standard Serial monitor requires pressing Enter after each note input. The solution involved implementing PuTTY, a terminal emulator downloadable from putty.org. To operate the system, launch PuTTY, select the Serial connection type, input your Arduino’s COM port, and establish the connection.

Components Required

• Arduino UNO
• Speaker: 0.25W, 8 ohms
