For some reason the code "half" works...
When I start my Processing code, my gLed is ON... should be off (set both Leds to LOW in the void section)
Also - when I start playing the game, I wanted the LEDS to blink when the ball hit the paddle... but that slows the entire game down tremendously...
My guess is that the lighting of the pins should occur somehow in sync with the serial event part of the code...
Here is the code... put in
BOLD the relevant parts...
ARDUINO CODE:int firstSensor = 0; // first analog sensor
int secondSensor = 0; // second analog sensor
int thirdSensor = 0; // digital sensor
int inByte = 0; // incoming serial byte
int yLed = 3;
int gLed = 4;
void setup()
{
// start serial port at 9600 bps:
Serial.begin(9600);
pinMode(yLed, OUTPUT);
pinMode(gLed, OUTPUT);
digitalWrite(yLed,LOW); digitalWrite(gLed,LOW);}
void loop()
{
// if we get a valid byte, read analog ins:
if (Serial.available() > 0) {
// get incoming byte:
inByte = Serial.read();
// read first analog input, divide by 4 to make the range 0-255:
firstSensor = analogRead(0)/4;
// delay 10ms to let the ADC recover:
delay(10);
// read second analog input, divide by 4 to make the range 0-255:
secondSensor = analogRead(1)/4;
// read switch, multiply by 255
// so that you're sending 0 or 255:
thirdSensor = 255 * digitalRead(2);
// send sensor values:
Serial.print(firstSensor, BYTE);
Serial.print(secondSensor, BYTE);
Serial.print(thirdSensor, BYTE);
//digitalWrite(yLed, HIGH);
digitalWrite(gLed, HIGH);
if (Serial.read() == 66) { digitalWrite(yLed, HIGH); delay(1000); digitalWrite(yLed, LOW); } else if (Serial.read() == 67) { digitalWrite(gLed, HIGH); delay(1000); digitalWrite(gLed, LOW); } }
}
