Week 12: INTERFACES : CIRCLE GAME
This week for HTM(A)A, our task was to add an interface to one of our existing boards from one of the previous weeks. micro-controller board and program it to do something. I decided to make a game with my phototransistor board...that I am apparently not very good at!
I decided to use processing for this week. The way the game works, is that you want to match the radius of the red circle. The grey circle is reading from the sensor. So by moving you finger far or close, you can control the size and color of the circle. To make this difficult, I added a time limit. To start out, 10 seconds is given to you...but every ten levels it reduces by 1 second!
I also included a enlarging "YOU LOSE" screen when time runs out...a very sad moment. I've seen this screen a lot! Not too proud of that. My High Score? Level 56! But anyways, check out the video and code below!
Here's my source code below:
import processing.serial.*;
Serial myPort; // The serial port
float k = 0.25; //alpha level for lowpass function
float cleanSignal; // global veriable for lowpass function
void setup() {
size (640,480);
// List all the available serial ports
cleanSignal = 0; //initialize global value for lowpass function
println(Serial.list());
// Open the port you are using at the rate you want:
myPort = new Serial(this, Serial.list()[0], 9600);
noStroke();
smooth();
}
