I made a music tool that can be used either in tandem with a computer or hooked up directly to a MIDI playback system. The computer in this case only does the translation of the notes sent by the Arduino through a MIDI to USB converter.
P.S: Hi Prof George. I made this to demonstrate one of the ideas that came out of today's brainstorming.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Parts List
For this project you will need:
-Arduino Uno ( or any other Arduino for that matter)
-HC-SR04 ultrasonic distance sensor
-5 pin din connector
-220 Ohm resistor
Step 2: Wiring
Connect all pins of the Arduino as shown in the picture.
Step 3: Code
The code I used is fairly simple and inefficient but it does a good job at showing the final product.
