We unboxed all the new toys: Arduino, buttons, expression pedal, and so forth. We plugged the Arduino in for the first time. We wrote a little program with the basics of Arduino. We used the MIDI library to send MIDI messages. And we used a button to control when to send MIDI messages.
Hardware is so fun!
