| which corresponds to the C and D notes of the 4th musical octave, including all their sharp and flat variations. Create 2 arrays, one of which will include the notes of a musical piece, and the other will contain the duration of the musical notes. In 4:4 time signature, I set a quarter note at 250ms. a half note as 500ms, etc. Then I called the playTone functions with the arrays as the arguments, and told the pi to begin playing the function when the button is pressed. For the sake of simplicity, I also initialized variables for note duration, with Q as a quarter note, H has a half note, etc. | which corresponds to the C and D notes of the 4th musical octave, including all their sharp and flat variations.

| + | This connected circuit contains a joystick, a active buzzer and a LED. The whole thing is ran by the joystick moving in the y direction. The joystick is a two axis analog device that allows for directional movement and a button press feature. When the joystick is moved in the Y direction, the active buzzer and LED light are both turned on but only as long as the joystick is being pushed/held in the y direction. The LED light is a simple output device that produces light when a electric current flows through it. While the active buzzer is a component that emits a sound when powered. unlike a passive buzzer, an active buzzer has an internal oscillator that makes it easier to control, meaning when a voltage is there it will generate sound. The goal and inspiration for this project was a hockey goal buzzer and light. | ||
