ard-usm2

Arduino Ultrasonic Musical Keyboard (Version 2), powered by Maker Uno. Uses the ssd1306 0.96" OLED Display (I2C) and u8g2 library for display.

Components

• Maker Uno (Arduino Uno can also be used, just update the pin constants accordingly)
• SSD1306 0.96" OLED Display (I2C)
• Ultrasonic Sensor [PING))) Ultrasonic Distance Sensor]
