For my Final Project I created a visual representation of the notes played by my drum sequencer. I paired Processing with Arduino, and sent numbers to Processing whenever a note played on my drum sequencer. Depending on the note, a different colored circle flashes in Processing. Here is the Arduino code: int buttonPins[9] = {14,Continue reading “Digital Electronics Final Project”

pressCallback and releaseCallback are variable functions. Each one holds a function as a variable. This allows for the flexibility demonstrated in our program today. When we change the onPress and onRelease functions, they are updated in the variable. #include “Button.h” Button buttonOne(36, 0); Button buttonTwo(35, 1); Button buttonThree(34, 2); Button buttonFour(33, 3); int ledPins[4] =Continue reading “Digital Lecture 10”

How does the button work in this code? In every iteration of the loop, the code checks the current state of the button and the previous state of the button. In order to determine if the button has been pressed, the previous state of the button would need to be low and the current stateContinue reading “Digital Electronics Lab 08”
