Project 2. Joystick Instrument - Using the Joystick module with the buzzer to create an [annoying] instrument.
The joystick module worked by taking an ‘x’ value input and a ‘y’ value input depending on how you moved the joystick. In my sketch, I decided to determine the ‘x’ value to be the duration of the note played and the ‘y’ value to be the frequency of the note played. Upon first experimentation, I discovered that the input wasn’t very accurate and jumped around a lot due to the values being so high (from 0-1023). With this information, I decided it would be better to map the input so that instead of playing the a frequency between 0 and 1023, it would play a set number of 11 frequencies in an array.
Overall, I felt that this project demonstrated exactly what I wanted it to do. If I had more time, I would have liked to develop a visual cue for this too, such as LEDs reacting to the input.
