This assignment was mostly straightforward,except for the part that involved making the numerous connections between the LCD and the Arduino. I used this tutorial to help me out with that. After the connections were made, the rest of it was fairly straightforward.

#include <LiquidCrystal.h> // initialize the library by associating any needed LCD interface pin // with the arduino pin number it is connected to const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2; LiquidCrystal lcd(rs, en, d4, d5, d6, d7); void setup() { // set up the LCD's number of columns and rows: lcd.begin(16, 2); // initialize the serial communications: Serial.begin(9600); } void loop() { // when characters arrive over the serial port... if (Serial.available()) { // wait a bit for the entire message to arrive delay(100); // clear the screen lcd.clear(); // read all the available characters while (Serial.available() > 0) { // display each character to the LCD lcd.write(Serial.read()); } } } |

import processing.serial.*; Serial port; void setup() { size(256, 150); //set size of the window port = new Serial(this, Serial.list()[0], 9600); } void draw() { // draw a gradient from black to white for (int i = 0; i < 256; i++) { stroke(i); line(i, 0, i, 150); } port.write(mouseX); } |
